Kids break their arms. It happens. Kids reacting like? That doesn't happen.

Walker here wakes up in the hospital to discover he has a cast on his left arm. To say this development shocks him would be like saying America was shocked when we first heard Bruce Jenner wanted to be a woman -- the signs were were there, but you just couldn't process it.

We're just going to assume Walker was on some meds, which caused this priceless reaction. We have a hunch that once the drugs wear off he's going to be pretty bummed that his arm is all dinged up. Maybe he should watch this video -- it's definitely good for a laugh.
