Nudity + Pain = Funny
I've never understood the appeal of taking off all of your clothes and running onto the field at a sporting event...or down a crowded street...or anywhere in public.
Personally, I don't even like to be naked around myself. I don't wanna see that mess! And believe me, me naked is a hairy mess!
But, if you're so inclined to run naked around town...I reserve the right to laugh at you when you get injured in the process. Honestly, I think what really makes this video funny for me is the reaction and laughter from the guy shooting the video. There's nothing better than a real, sincere, full body laugh. So join me, and the cameraman, in laughing at this numb nuts.
