I'm in need of a good comeback?

so last night i went to my friends house, he was just having some people over so i was planning on just watching them get drunk and laughing at them. anyways, long story short, i ended up making out with this guy for a while and then he was like, let's just cuddle for a while and i was like no we should just makeout some more. So he was like, if you can tell me my name, i'll kiss you some more. the crappy thing was, i had forgotten his name. So then today i decided to facebook him and was like "i facebooked you, how's that for remembering your name, david". A little while later i get this response of "about time!". I'm speechless, how am i supposed to respond to that?! I have to admit he plays the game better than me, I have finally met a worthy opponent and for i think the first time ever, i can't think of a response. So i need some good snappy comebacks, thanks
