Curb Your Enthusiasm, Season 4

Marty:
Hey Lar, you ever hear of Denta Friend?

Larry:
Denta Friend? No.

Marty:
It's a new sonic toothbrush that would really get rid of your plaque.

Larry:
What are you talking about, get rid of plaque. I don't have any plaque.

Marty:
My cousin's hygienist told me you have plaque.

Larry:
Your cousin's hygienist told you I have a lot of plaque?

Marty:
What's the big deal? Plaque is not a serious disease.

Larry:
First of all, number one I don't have any plaque...

Russian Man (with Wife/Translator):
(laughing)

Larry:
Number two, she shouldn't be telling you, that's a breach of patient-hygienist confidentiality.

Jeff:
There is no patient-hygienist confidentiality.

Larry:
You're so wrong.

Susie:
It's unethical, not legally like a doctor or a lawyer, but its unethical is what he's saying.

Larry:
It's totally unethical, and I don't have any plaque by the way, do i have an electric toothbrush?

Cheryl:
He has an electric toothbrush.

Larry:
How often do I floss?

Cheryl:
At least twice a day.

Larry (talking to translator):
Tell him I don't have any plaque, okay, did you tell him that?

Marty:
You have plaque.

Larry:
Do you wanna have a plaque contest with me Marty?

Marty:
Let's have a plaque contest.

Larry:
Anytime you want.

Marty:
Anytime you want.

Larry:
Fine, you want to?

Marty:
Challenge me just like you do in golf.
