Spider-Man Knocks Himself Out

Call it a Spider-Sense Malfunction. 

If you're a kid, and Spider-Man shows up at your birthday party, you know things are about to go down! For one birthday kid, though, Spider-Man wasn't the most graceful of creatures. 

You can see in the video below that things start off pretty well and Spidey is doing his flips and tricks (he did come from a showbiz background afterall) and the kids are loving it. But then during one flip, the actor lost his balance and hit the floor like a punch from the Rhino. 

Let's see that again. 

Oy. Poor Spidey...and poor kids. Nothing like having Spider-Man have a concussion at your party. At least you'll have a story for the kids at school over the weekend.
