9. Too Much Coffee

A: How many cups of coffee have you had today?!

B: I don't know, three, maybe?

A: Don't you think that's a little too much?

B: No way! Coffee is good for you.

A: Too much of anything is bad for you!

B: What about water?

A: Sure! People drown all the time.

B: Well, I'd happily drown in coffee.

A: Did you know coffee stains your teeth brown?

B: Does it, really?!

A: Yes. Your teeth will rot out if you drink too much.

B: I'd better stop, then; girls like nice, white smiles!
