Some Like It Hot (1959)
Osgood Fielding III: If I promise not to be a naughty boy - how about dinner tonight?
Jerry/Daphne: Sorry. I’ll be on the bandstand.
Osgood: Oh, of course. Which of these instruments do you play?
Jerry/Daphne: Bull fiddle.
Osgood: Fascinating! Do you use a bow or do you just pluck it?
Jerry/Daphne: Most of the time I slap it.
Osgood: You must be quite a girl.
Jerry: Wanna bet?
