cold diarrhea 

the punch line of an insult used in northern New Jersey during the 60's and 70's. made no sense then, makes no sense now, but still kind of funny.

carly: man, you think you're hot shit in a wine glass, but you're just cold diarrhea in a paper cup.
farley: that's so funny i forgot to laugh!
charlie: you're both about as funny as a cigarette machine in a cancer ward.
carly and farley: huh?
