In the interest of safeguarding and preserving American humor, I feel it is my civic duty to respond to your misguided attempt at humor this afternoon. In case you’ve forgotten, I’ve recounted it below:
You: … and here’s your receipt.
Me: May I have some extra packets of ketchup, please?
You: That’ll be $2 extra! Ha! I’m just joking. Here ya go, buddy
In case my death stare wasn’t enough, I’ll put it to you a different way: Shut up. Just… shut up. And don’t ever try to be funny again. You might hurt yourself.
