Thats one of the oldest lines used on hecklers, not sure why it raised such a fuss but hey she's a comedian and they are supposed to have a comeback for all occassions...the dude was being a dick so she called him out on it no biggie.
I like her and find her stand up to be pretty funny. Her show appearances not so much because they have to censor the shit out of her.
