Hilarious.

This is the conversation Rob had with Ray, our super today.
(Please read all Ray parts with a VERY heavy NY accent)

Rob: Hey, Ray, how you doin? Haven't seen you around lately
Ray: What? You think this building cleans itself?
Rob: No, man.
Ray: You think there's a button around here that you push and the place just cleans itself?
Rob: Uh.. no. I just haven't seen you.
Ray: Well I aint seen you either. Dont mean I aint been here cleaning.
Rob: Um.. okay, Ray. Have a nice day.

Seriously, don't mess with the guy, he's been cleaning, okay?
