this will give me nightmares for awhile...

Primeape doesn't look angry, it looks really, really, REALLY happy. Like on that episode of Ren&Stimpy

Yeah, but that doesn't stop this image from being "shit your pants" frightening.

Remember, a big toothy grin is many primates' way of saying "look at how many giant f***ing teeth I have, so don't mess with me."
