when i was younger fishing in a local canal i caught a leather belt. then bass fishing in the hamble river i caught a pair of sunglasses. from the boat i have caught lumps of rock, coral, pieces of wreck. a friend of mine was recounting in the pub of the monster he caught out his local canal, he played for about 15 minutes skillfully trying not to break his 1.5 lb hook length till it came to the net and it was a coconut! its amazin what people have caught over the years, great subject!
