Melvin Udall: Never, never, interrupt me, okay?

Even then, don’t come knocking. Or, if it’s election night, and you’re excited and you wanna celebrate because some fudgepacker that you date has been elected the first queer president of the United States and he’s going to have you down to Camp David, and you want someone to share the moment with. Even then, don’t knock. Not on this door. Not for ANY reason. Do you get me, sweetheart?
He of course later redeems himself mostly because of his love of a good woman played by the wonderful Helen Hunt.
