"So Chris, are you with Nina, or Joanne?"
"Hmm...let's see... Joanne broke up with me, and got with Nick, and then broke up with him, got back with me, then went to Jonah, then back to Nick, and again with me, but I was sick of her boyfriend tagging, so I said it was enough, and got together with Nina."
