A student in a psych class is asking his professor about sexual fetishes.

Student: Do you know the scientific names of most of the sexual fetishes?

Prof: I believe I know just about all of them, I’ve been teaching psychology for over 40 years.

Student: well what do you call a person who is aroused by dead people.

Prof: easy, that’s a necrophiliac.

Student: how about someone who is aroused by feces?

Prof: that’s not so common but I believe they call those people coprophiliacs.

Student: Wow, you know a lot. Ok, what about me? I’m aroused by sticking my junk into a bag of cashews. What would you call me?

Prof: well I’d say your fucking nuts.
