Seinfeld, Season 7

Jerry:
I still can't believe, you're going out on a blind date.

Elaine:
I'm not worried. It sounds like he's really good looking.

Jerry:
You're going by sound? What are we, whales?

Elaine:
I think I can tell.

Jerry:
Elaine, what percentage of people would you say are good looking?

Elaine:
25 percent.

Jerry:
25 percent, you say? No way! It's like 4 to 6 percent. It's a 20 to 1 shot.

Elaine:
You're way off.

Jerry:
Way off? Have you been to the motor vehicle bureau? It's like a leper colony down there.

Elaine:
So what you are saying is that 90 to 95 percent of the population is undateable?

Jerry:
UNDATEABLE!
