Punch That Pony

So I have a friend who is obsessed with me punching ponies. Actually he's just obsessed with pony punching it seems. And anytime I have a "moment" he'll ask "So did you punch a pony?" So that's usually the new phrase of how angry someone can get. Pony-punching anger. Anyway, check out the brief conversation I had with said friend at work:

me: "my hand itches. what does that mean?"

j: "huh?"

me: "you know when people say your ears itch, someone is talking about you"

j: "uh.."

me: "oh i mean when your ears burn! when your ears burn someone is talking about you."

j: "oh yea. thats right."

me: "so my hand is itching. what does that mean again?"

j: "it means you need to go find a pony to punch."
