House Party, Friendship.
A group of 20-somethings are sitting around, drinking beer and talking. A guy lights up a cigarette:

Drunk Girl: You smoke?! Gross! That, like, causes cancer and stuff.
[Several people nod in agreement.]
Cigarette Guy: Actually, it’s just a coincidence that tons of smokers get cancer.
Drunk Girl: Well, why don’t you smoke weed instead? It smells better.
