(A guy comes into my register with a pretty standard basket of groceries.)

Me: “Sir, did you only get one pint of Ben and Jerry’s?”

Customer: “Why?”

Me: “Well, it’s ‘Buy one, Get one free’ this week.”

Customer: “Hold on.” *runs off and returns a minute later with 9 more pints*

Me: “You must really like Ben and Jerry’s, huh?”

Customer: “I have a pregnant wife.”
