I guess I'm the guy to call at 3am. Not that I mind, mind you. I just find it funny that I've got call-waiting beeping at me in the dead of night while I'm chatting with a drunk friend. I go to answer and its another drunk friend. 15 minutes later a third, and so on into the night.
I'd love to claim massive popularity, but I think maybe I'm the only guy who answers his phone in the dead of night.
