Growing up in Satellite Beach Florida, an island on the ocean side, separated from the mainland by the Indian / Banana River, we used to go fishing and even shrimping off Mather's Bridge (a crappy little rickety bridge over a narrow stretch of the river), so one day when I was little I was fishing with my sister and while she was going to bait the hook her pole fell so that it was laying on the walkway with the hook about 2 inches in the water, she went to grab it and when she lifted it up there was a huge (I was like 5 years old so it was huge to me) crab holding on to the line and refused to let go no matter how she shook it. Finally she dropped the line back in the water trying to get the crab to leg go which it did, when she pulled up the line not more than 30 seconds later there was a 5lb catfish on the hook.
Weirdest damn chain of events ever. I just reminded her about that the other day, always fun to have those random memories to share with a sibling!
