The other night at work one of the servers was standing next to the bar, flexing his arms obnoxiously.

Server: Do my arms look big?
Me: (annoyed) [server's name], what are you doing?
Server: (not getting it) I lift weights.
Me: No, what are you doing right now?
Server: (really not getting it) Showing you my arms and asking if they look big.
Me: (sigh) Nevermind.

I mean...c'mon!
