An ATV is not all terrain.

Here's your daily dose of "It's good to know there are some people dumber than me," a guy tries to head down a staircase -- without a bannister -- on an ATV.

What could possibly go wrong? How about everything?

Look, the best innovations often take lots of trial and error, but we're not exactly sure what the end game is here. Does he think he's just going to go down the stairs easy peezy without any problems? Maybe when he fell the brain went properly back into his head and he realized just how silly this whole stunt was.

Anyhoo, next time someone says, "Take the stairs," let's hope he understand exactly what that actually means.
