Overheard while queueing up at the supermarket to buy some emergency supplies:
cashier: "Would you like a bag for that sir?"
confused old man: "Sir? Sir?!? There's only two of us."
I have no idea what he was talking about there, for in fact there was only one of him.

I don't get it either. I only translate, not explain reasoning.
