Best Comeback?

Does anyone know any really interesting, funny or humiliating comebacks? The only non-explicit one I know of that's actually GOOD is "Thanks for sharing your unique opinion" ;) And please, no "That's what she said" or "Ya mum" ones. If I wanted something like that, I'd go google "Obvious signs of people who are dickheads"

No 'yo momma' jokes ? Damn, I love them.

Yo momma's so fat she cut her leg and gravy came out.

Sorry. Trying to think of a comeback without 'yo momma' jokes is, for me, like trying to box Mike Tyson with one arm tied behind my back.

Someone asked my friend, directed toward myself, "Where did you find this guy."

I intervened saying in a cockney child's accent, "Mummy said I came from under a rock."

I told your momma to act her age, and the bitch dropped dead.

Tee hee.

"If I ever wanted to hear from an asshole, I'd fart"

"Does your mother know you're outside without your helmet again?"

"I don't know what your problem is, but I bet it's hard to pronouce"
