When Carmen finds out that her boyfriend Jason was cheating on her for a month, she calls him over to take his stuff back, then when she comes over, Carmen walks in carrying his stuff and wearing a VERY revealing outfit, she then tells him not to bother calling him, throws his stuff outside and tells him that he can go to hell.
Carmen: I just want to let you know, if it doesn't work out, and you want to come back here....don't. Now that you know what you're losing, go to hell!

Doubles as a Moment Of Funny, but there is the time George zinged Benny's mom once she was out of earshot during the episode where we get to see how much of a Complete Monster she is.
George: Damn! I think some flowers died as she walked past.
