If you don't believe that this man has the most game on Seinfeld, you must be an anti-Semite!
This conversation (From The Showerhead episode) has Jerry trying to convince Uncle Leo to leave his girlfriend Lydia and lead a more RVF-friendly lifestyle:
UNCLE LEO: It's about time you called your uncle. We've got to do this once a week.
JERRY: [to himself] Once a week? [to Leo] So how's Lydia?
UNCLE LEO: Ah, she's a real tiger.
JERRY: I don't know how you do it.
UNCLE LEO: What?
JERRY: A man like you, limiting yourself to one woman. I don't know. But it's none of my business.
UNCLE LEO: What are you talking about?
JERRY: Well...
UNCLE LEO: Look at this, I told them medium rare. It's medium.
JERRY: Hey, it happens.
UNCLE LEO: I bet that cook is an anti-Semite.
JERRY: He has no idea who you are.
UNCLE LEO: They don't just overcook a hamburger, Jerry.
JERRY: All right. Anyway, the point I was making before Goebbles made your hamburger is a man like you could be dating women 20 years younger. Come on Uncle Leo! I've seen the way women look at you. When's the last time you looked in a mirror? You're an Adonis! You've got beautiful features, lovely skin. You're in the prime of your life here. You should be swinging! If I were you I'd tell this Lydia character, “It's been real,” move back into that bachelor pad and put out a sign, “open for business.”
UNCLE LEO: Believe me, I thought about it. But she is so perfect in every way. I can't see a flaw.
JERRY: Well, keep looking.
