Made our shipping guy laugh yesterday.
I went out and asked if he'd received a package addressed to me. He said "We don't sleep together, so it's polite to say "Hi, how are you doing?" before you ask.
I said "Well, as tempting as the idea of sleeping with you is, so I don't have to do small talk, I don't think it's a good idea."
His jaw dropped, then he laughed.
