Banging your head against a wall uses 150 calories an hour.

well did you know that you kill about 50,000 brain cells from a simple bang on the head, so if you want to lose a lot of brain cells while exercising, then thats the way to go.

kyle said i do that all the tiime

OK who the heck banged their head on a wall to get this information

probably get a concussion out of it too.

good way to excersice!

Banging your head removes calories and gives you a bleeding head! Fun huh?

hahahha... thats so cool! XD

GREAT!

I'm quite sure that it's 300 calories an hour.

I believe they forgot to mention the whole story. Banging your head against a wall will make you lose weight -- your brain cells weight. No wonder why all those hot "Miss America" and "Miss Universe" look so fine! The secret is out. I'm spreading the word!

how would you know that!?!?!?
