Exploding head: This is a gif (one of my personal favorites) of some geek who's head got blown up!!
Dead Pac: This, as you probably know, is 2 Pac. This is a picture of some one shooting him in the head! (based on real life!!)
Headless: This guys head's been chopped off but his neck bone's still twitching (sweeeeeet!!)
Head-Light: This looks a bit like Hell Raiser, I don't know if it is or not but there's something up with his face!!!
Head-Lice: This is the same guy as in "Head-Light" but this one's got an infestation in his mouth!!
Pin-Head: Now this is the real Hell Raiser, look how the spikes pop in and out of his blue bonze!!
