Former Jackass star, and past Morning Rehab guest Steve-O recently visited San Antonio and thought it would be a great idea to backflip off a bridge right into the famous River Walk.

He immediately regretted it. Beside the fact that the River Walk water is notoriously disgusting looking, it's also only 4 feet deep.

Luckily, Steve-O escaped without injury but I'm sure he'll think twice about doing something stupid like that again.....but then again...that IS what he's famous for right?
