Larry David: Curb Your Enthusiasm1999

Larry:
I'm wondering, uh, in case I break into some Spanish or french... may I use the familiar tu form with you people? Instead of usted? Because I think usted is gonna be a little too formal for this crowd. I feel already I've established the kind of rapport than I can, I can jump into the tu form with you! That quickly! I'm taking a tu liberty with you, I'm gonna use the tu form, and that's it! You can't talk me out of it. You know, Caesar used the tu form with Brutus, even after Brutus stabbed him. He said "et tu Brute," and I think that's a little too informal when someone's trying to assassinate you.
