I thought this might get some interesting feedback. I'll start with a couple.
  My brother in law and I were Bass fishing one afternoon. He was using a broke back top water plug and hitting along a bank under some overhanging branches. On one of his casts (turn out it would be his last of the day) he over shot his mark and snagged one of the over hanging limbs. The next thing I knew his line was over my shoulder and he looked like he was trying the pull the tree up by the roots as he yanked on the plug in an attempt to pull it free. I could feel a little cold sweat on the back of my neck as I anticipated how badly this situation could turn out. I immediately fell to into a slump hoping to avoid spending a few hours in the ER. About the time a hit the deck I heard a whistling sound zipped past my head and I heard what sounded like a small girl squealing behind me. I looked around and there hanging from the skin right next to his eye was the plug. It had tow of the three hooks on one of the treble hooks buried in the meat right next to his eye. I offered to remove it with mu needle nose pliers, but some reason he chose a ride to The ER instead. So much for avoiding a trip to the ER
  On another occassion I was fishing on the bottom of a river and was using a 1.5 oz weight to anchor my line in the current. I hadn't had any bites in a while so I decided to check my bait. While reeling in my line got stuck on something on the bottom. Without thinking I yanked back on the line. The next thing I member is looking up at the sky, with a terrible headache and not knowing how I got on my back or why my head hurt so bad. After regaining my composer I noticed that the only thing left on the end of my line was that !.5 oz weight. Suddenly the whole situation became clear especially when a saw the goose egg that rose up on my forehead!

I hooked a backpack that had a pole hooked to it. There was nothing in the backpack. I was fishing off of a bridge that crosses a channel in my local park. I'm guessing that someone hooked the backpack while casting, and somehow dropped the pole when the bag fell. It was a 202 on some nameless pole, and the reel was now junk. Not so interesting, but I was still shocked to reel it in.

Lohycore, seems like several people on this sight complain about not receiving the gifts they have coming for joining up, and you bypass the redtape and go hook your own

I have caught two birds while fishing on the Oregon coast. One while salmon fishing, and one while fishing for sea bass. One of the two stayed under the surface while I brought it in, so I was quite surprised when I saw it. Releasing a bird is ten times more difficult than releasing a fish by the way. I have also been hooked by other people three times. Once by a clueless fly fisherman, and twice by my best friend. Sometimes it is not about what you catch, but what catches you.

My uncle to us on a guided fly fishing trip. The guide was great. Neither of us were fly fisherman. I'd probably tried to cast a fly rod maybe 100 times before that trip. The fish were cooperative and my biggest problem was my back cast, when I was close to or on the bank. The guide takes me to a little pool that formed from a trickle of water in and out, but was stuffed with fish. On a back cast I hooked a tall pine tree. The guide goes back and unhooks me, while holding the fly, he says, "go ahead." I actually turn around giving him a look like he told me "Santa Claus is real, hates children, is allergic to cookies and miilk and beats his reindeer." I'm thinking I've got a 9' rod and you're wanting me to proceed to cast... and you're pinching my fly???? He says, "Go ahead." I do and everything works out well. Once I hook the tree again, he untangles me and repeats, "Go ahead." This time I hook him and I've already got the rod to 2:00 before I realize I've landed the largest catch of the day. I gave him a $100 tip.

Hey, you know how the old saying goes, "you got to make your own luck..."! It was a camo print canvas backpack, so my wife tried to wash it and see if it was salvageable, but no go. That's okay, we caught plenty of fish that day, and a funny story to go along with it.

Lohycore, those stories about the cormorants are probably true. One of the two birds that I have caught was one of those. It dove and grabbed a small white jig I was using at night while fishing for black sea bass off of a jetty. ODFW has even started hazing them to stop them from eating salmon fry.

Yeah, I believe most of the stories, I just haven't caught one myself. They are fairly aggressive birds, and will sure sound-off when disturbed. My wife has made the comment that they are noisier than gulls early in the morning. I may have followed-up with a comment suggesting I know of something else even noisier when disturbed early in the morning, but will not repeat the conversation that followed. Suffice to say that it ended with her saying "shut up and fish!"

a few years back while fishing for sturegon off the old San Mateo bridge, i hooked a piece of rebar that was partially buried in the mud of S.F. bay it took me about 20 min to get it to pull of of the mud and get it up to the edge of the bridge so we could lower a large crab net down to " land " the rebar. as it turned out the rebar had at one time been used as a ladder on the side of the bridge pilings and it had rusted off and settled on the bottom. I was using a double hook set up and the hooks had locked with one facing in each direction around the rebar, what a fight, but my buddies even to this day won't let me forget my heavy catch, by the way the rebar weighed in at about 25 lbs.

An alligator.

Yes, an alligator. And at a pond that isn't supposed to have any at that. It at a brand new buzzbait I had not even had for twenty-four hours that I was fine-tuning on my baitcaster. It was a female and still had babies around, so that was probably why.

Lohycore reminded me of some other items I've caught while fishing. The best, a canvas tackle box with many usable lures. Several anchors all of which are servicable. One I was able to retrieve from my boat, the other 3, i had to get a $5 lure back and it was summer, so I just went swimming and came back with anchors and my old lure. Two were 8 #, one was 16#, the one that I got into the boat was a river anchor with arms that expanded out. I ended up pulling a small tree w my plug knocker on that one. At Lake Tahoe, while swimming, we found a Lands End beach towel, still in the plastic wrap. It washed out well and we still use it. I've caught fishing poles, none have been any good. I've actually caught a shoe and a rock, but the rock was small. My mom, however, caught an enormous rock while fishing for fluke in near Duxebury MA. It must have weighed 1.5# or more. The fact that she boated it was impressive to me.

I was saltwater fishing in the bay for fluke and my buddy next to me hooked something big. I got the net ready and when it got to the top it was an unopened 12 pack of beer.  It must of fell off a boat. That was the big one of the day.

Dang, I'm gonna have to start trolling the bottom of lakes for Christmas presents!
My weirdest snag would have to have been when i was reeling in a nice sized Largemouth off of my Uncles boat. I had cast into a mess of cover about 10 feet from shore, walking a zara spook back and forth. This 3lber, smashed it off the top of the water like you would see a Great White do to a seal. Anyway, whilst reeling him in and trying to get him off the bottom, I suddenly felt some extra dead weight tugging on the line! Finally got him and what was on my line off the bottom, reeled it all up, and it turned out to be a 3lb 7oz Largemouth bass, and what I would guessed to have been in the area of a 1 1/2lb pair of Levi Bluejeans. I guess someone had a pretty good time on the lake in the area I was fishing. Nothing in the pockets, just a pair of wet jeans that I quickly tossed in the trash, but not before getting a photo of it and that Bass! Crazy day.

i was bass fishin on muskegon river thought i caught something big reeled it in was an old rusty bud light tall boy can but the part that startled me was when all the sudden three huge crawfish shot right out of it right at me soon as i got my hands on it.

I have posted this story before on this site on a similar topic but here it is again: One time, when I was fishing, I cast out with a Rooster Tail and got snagged on a big rock. Well, I pulled and pulled until the line broke at the knot and I lost the lure. Anyways, several weeks later I was fishing the exact same spot with the exact same kind of lure (a yellow Rooster Tail) And on one of my casts I felt some pressure but it felt too light to be a fish. Well, as I reeled in I was amazed at what I saw. It was my Rooster Tail I had lost just a few weeks earlier! Somehow I had cast just perfectly and snagged it. I was left sitting their in astonishment starring at my two identical lures and wondering what the mathematical odds were of catching that lure. It still amazes me to this day and reminds me why I love fishing so much, its because you NEVER know what's going to happen!

I got snagged on a shopping cart last week.

A few weeks ago my son and I where fishing in Lake Erie for walleye and smallies.I got snagged, and began the usual steps at getting it out. I was pulling line tight then opening bale on the reel, which works most of the time. However this time it worked to good. I gave a good yank and the lure comes whizzing at me...right towards my face. I put my hand up to block, and the treble hook sunk right into my hand. Then right after it hit me i got it tangled on my dock line. (see picture) What makes this kinda funny is that my last name is Fish. Everybody at the ER had a good laugh.

Not as good as some, but I was dragging a 7" plastic work across some lilly pads and right when it dropped into a hole I had a bite. I thought it was a good large mouth until I fought it in and found the largest frog I have ever seen on the end of my line. It was at least a foot long toes to head. I managed to get the hook out of him and release him.

That wasnt my first frog. This past spring I had one take a Joe's Fly. Crazy.

Well, my buddy hooked a barracuda in the Florida Keys, then it hooked him. Without pictures, most stories are just stories. Enjoy the pics.
