So apparently this woman was epileptic, and had a seizure while she was gobbling his weiner. This caused her to bite down. Hard. The man, who panics because a)his wife is having a seizure, and b)his wife is biting his penis. BTW they were in the kitchen when the mood struck I guess, because the closest thing he can grab is a fork. In his panic, he proceeds to hit his wife on the head with the fork, thiinking this will cause her to disengage her mouth, causing the tiny punctures.
So I'm sure there are valuable lessons to be learned from all of this, but I personally just find it hilarious.
