A girl visits her boyfriend on a Friday night

Girl: Is that a banana in your pocket or are you just happy to see me?

Boy: Actually, it’s a banana. They were on sale.

Girl: OK… is that another banana in your pocket, or are you happy to see me?

Boy: It was a 2-for-1 sale.

Girl: Alright, fine… is that yet another banana in your pocket?

Boy: Well, with savings like that, I’m not going to buy just two, am I?
