"I know you are, but what am I?"
a good comeback would be " look who is talking" "there's a mirror hun, woops! it broke!!" "haha i wouldn't be talking if i were you."
If someone calls you fat, a good comeback is 'I may be fat, but you're ugly, at least I can diet!' though, the best comebacks are said in your head. If you say it in ur head, u get the satisfaction of knowing more than the bully and will normally smile. Bully's hate that and after a while will probably get bored and stop.
This does not need a comeback. This is technically a compliment from someone, so stop taking everything so literally.
tell them i know you are but what am i and keep doing that until he gos away
Say "that person must be very pretty then"
my pleasure(if you like them or something)
a good comeback to that is you wish.
A good comeback could be: So ? Or : And your point is ?...
Yo' mama! Is a good comeback
That was a pretty good one, for anidiot (or half-ass)
* Make a good comeback. * Turn the other cheek.
