He's like a mammary GPS

During a conversation about obesity at BA dinner -

Richard: "General rule: breasts should go past bellybutton, not the other way around."
[I look down, Richard looks confused]
Me: "I was just checking how this slouched posture affects things."
Richard: "It doesn't. I'm aware of the location of your tits at all times, don't worry."
[pause]
Richard: "You really shouldn't let me near alcohol."
