Jerry: I have never seen one episode of "I Love Lucy" in my life ever.You don't hear about lactose intolerance anymore, for some reason. Or I don't. Maybe you do.
Donna: That's amazing.
Jerry: Thank you.
Donna: Is there anything else about you I should know?
Jerry: Yes, I'm lactose intolerant.
Jerry: I have no patience for lactose. And I won't stand for it. Uhm, I'll be right back. (Goes to bathroom)
