It's okay to be a kid at heart, but it might just be smarter to leave it at that.

A grown man fell off a water slide he was riding near Austin, Tex.

Gotta give this guy credit for being able to laugh at what happened, what with all the hashtags he used. We're guessing he may think twice the next time he has a chance to go down a water slide, though.

And it's a good reminder that there are certain things grown men should leave to little kids. You know, things like drinking a box of Capri Sun, wearing a hat backwards or wearing floaties. There's a time and a place and for this guy that time was before puberty hit.
