Conversations with My Doctor I

Dr: You’ve lost a lot of weight.
Me: I’ve gained five pounds since the last time you saw me.
Dr: Well, you know what they say. Okay, let’s see, you finished taking Z-pack a week ago . . .
Me: What do they say?
Dr. What?
Me: You said “you know what they say”. But I don’t know what they say.
Dr: Oh, people say all sorts of stuff.
