To carry this to the point of ridiculousity:
Let's review this carefully. Kramer describes someone, who I agree is Jerry, as having "flared nostrils." Ticket lady has to think about a person she's seen who looks like what George described. She applies that description to the person she's seen with..."flared nostrils." I submit to the jury that she thinks George has described Jerry.
No, I didn't infer a horse face from a big head. I inferred flared nostrils from flared nostrils. Yes, I hope I straightened you all out. :-)
