From Overheard in New York, via Gawker:

No, Seriously — Let's Hit It

Old Chinese lady: Ex-see-cus-see me.
Old Chinese lady: Ex-see-cus-see me!
Gangsta: Man, what are you excusing me about? Fuck you!
Old Chinese lady: Fuck me? Ok, take-a off the pant.

Stairway in silence.

Old Chinese lady: Ex-see-cus-see me!
Gangsta: Sure thing, ma'am. I'm sorry.
Chinese kid: And that's why we respect our elders.
