What we tend to forget: Perhaps FFC was drunk when he wrote this part of the script. The whole scene is crowded with drunk people: Pentangeli, Deanna, Fredo, Manolo the landscaper, Connie, Geary's wife. Even Michael who never drinks, has champagne during a business talk and wine when they have their hundred-years-toast.
So I'm sure FFC must have been drunk when he wrote this part of the script.
