This is what I came up with for the dialog:
Man 1: Oh quit supposing will ya. You’re beginning to sound like some of these guys around here.
Guy in background I can’t make out. Calling for Mike maybe?
NY guy: Now don’t be that way. You’re right Arthur. He’s crazy. C’mon Arthur, we’ll make some vitamins.
Guy: I’m not Arthur.
NYguy: Nah, I know it. But they don’t know it. You take 2 pints water, 1 pint ketchup, vitamins D and E, for iron.
