- Coffee keeps you awake. That's a well known fact! Why are you so pig headed about it?

- I tell you it's a new scientific theory. People only think coffee keeps them awake. Those kind of people are nervous wreck and couldn't sleep anyway.

- So I say if you don't sleep at night it isn't the coffee it's the bunk. Do you get it?

- I guess so...

- You guess so, what's it mean?

- It's the bunk.

- Yes. But do you get the play on words?

- Oh Jimmy, you don't need a play on words.

- Any time anybody tells you that coffee makes you sleep you don't need a play on words to know it's the bunk.

- Don't you understand? Don't you understand it's funny?

- It means if you don't sleep at night, it isn't the coffee that keeps you awake, it's the bunk! ...The bed! The bed!

- With me it's the coffee.

- Ooh!
