Ever heard of catfish noodling? I first saw it when I was watching older episodes of Cougar Town (which is actually pretty funny if you can get past the name - and not all about older women chasing younger men). I thought it was a joke until saw I videos of real people doing it on YouTube.
Click here or search "catfish noodling" on YouTube to see for yourself. The person that came up with this idea in the first place must be nuts. Probably from whatever chemicals caused such mutant fish in the first place, lol.
