lmao. There was some show I saw, I think it was on the History Channel. They were at some river in the South and they spent the entire episode with some guy who insisted that there was a giant 10-foot catfish in the river (maybe multiple giant catfish? I can't remember), and that the catfish was responsible for the various pets and occasional people who went missing and were never found. They went off and talked with ichthyologists who talked about limits on catfish sizes, and I forget who else, exploring all the edge cases which might allow a giant ten foot catfish to live in the river. And at the end of the episode, they're talking to the guy again, going over their findings that it's possible, theoretically at least, that at a very very edge case, this giant catfish might exist, and the guy was like, "I knew it! Everyone around here keeps sayin' it's the alligators, but I jes' knew it was th' catfish!"
