A Running Joke

(I visit two of my friends at their house while we are all at university. Friend #2 is notoriously lazy. I overhear the following conversation.)

Friend #1: “I’m going to the kitchen. Do you want anything?”

Friend #2: “Oh, I’ll have whatever you’re having.”

Friend #1: *grinning* “In that case, I’ll have a jog followed by a cold shower.”

Friend #2: “Ah, go to h***.”
