I saw this string the other day and I couldn't think of any at the time. I'd say J. Peterman had some great lines and he delivered them impeccably. When finally receiving JFKs golf clubs after being thrown out of a truck and dragged on the ground for miles, from Elaine he says,
"I had no idea JFK had such a temper."
Also, when she goes to Burma to ask him to sign the invoice for the Fur Hat. He says,
"Elaine, I'll have to see this hat."
Something like that, hilarious!
