Well

Friend 1: Well?

Friend 2: Hole in the ground you get water from.

Friend 1: Huh?

Friend 2: You said well. But you said it like you were asking a question. I thought maybe you didn't know what a well was. So I told you.

Friend 1: Shut up.

Friend 2: Or it could also be the hole in old school desks you got ink from.

Friend 1: I was asking about your date last night.

Friend 2: Oh I see! In that case, the word 'well' can be used as a shorter way of asking how my date went. Especially if I had no idea what you were going on about.

Friend 1: I hate you.
