Spiderman!

My little Spiderman has been trying to do this for a good 6 months after seeing a kid on YouTube do it. He was amazed when he saw a kid dressed like Spiderman scale his wall and he hasn't stopped trying since. He has finally mastered it...and he won't stop doing it. He's starting to freak me out because it seems like he gets a little higher each time he does it. He has to just let go and jump down so I'm waiting for a broken bone. I told him not to do it anymore...after I got the picture. :-)
