Is this story about an eel devouring a man's internals plausible?

Heard it on the Radio today (Bad News, Happy Music) being reported as true by a very very intelligent and professional DJ, very well spoken and always checks his facts. I think he has been proven wrong by listeners like twice since he has been in broadcasting so if he said it I trust it.

Do it. You won’t be disappointed. (Putting them up there is bad enough, but shooting them back out again? :eek:)

This reminds of that dude who was killed after stuffing horse cock up his arse (still attached to a living horse, perforated bowel or something.)
