LoL
one of my buddies from camp pendleton told me he got really screwed up by sparying that canned air stuff that people use to clean off keyboards and stuff. I aint sure what brand it is but he said it hit him like NOS, cept when he inhaled to much the shit felt like it froze everything from his nostrils down to the bottom of his lungs and he passed out, fell face first onto the floor of his office and got evil rug burn on his forehead.

Canned shit is dangerous anyways, so i wouldent recommend doing it.
