Funny Video!!

Anybody looking for a humorous milksnake should go to YouTube and search Clint's Reptiles (milksnake) and at the end the snake starts biting itself multiple times trying to eat itself, lol. Clint's hilarious!!

Sorry to be a "wet blanket" but I find nothing funny in that: snakes that bite themselves are either hyper-hungry (& very misguided) or having internal pain
(like from parasites). Sadly I've seen a wild-caught snake do exactly that, right before it died.

The examples you gave are completely valid and I agree aren't funny. However, since there's no way of finding out if either of those things are true and are the cause since kingsnakes are cannibalistic it's possible it smelled itself and tried eating it. Which I find humorous. To each their own.
