The wackiest non living thing Ive caught was a pair of sunglasses while bottom fishing.
Living, off the top of my head, Ive caught a gull, plenty of frogs, a huge salamander, squid, plenty of snails, a hermit crab, and a few octopus.
have been in a boat with someone who snagged a gull, while taking the hook out of the mouth the gull decided to throw the plyers into the lake.
