Donna (the girl in the restaurant)

— Would you like to learn to tango, Donna?
— Right now?
— I'm offering you my services, free of charge. What do you say?
— I think I'd be a little afraid.
— Of what?
— Afraid of making a mistake.
— No mistakes in the tango, Donna. Not like life. It's simple. That's what makes the tango so great. If you make a mistake, get all tangled up, just tango on.

— Michael thinks the tango's hysterical.
— I think Michael's hysterical.
