newman's funniest moment

Imho it would have to be when they were going to kidnap the dog that keep Elaine awake by barking and Newman started singing "How much is that puppy in the window".

Haven't seen many other posts on this thread, but I think the most hilarious Newman moment was when we and the gang learn that he works for the Post Office and George asks, "Aren't those the guys who go around blowing people away?" and Newman ominously replies, "Sometimes."

Followed by Jerry asking, "Why is that?" and Newman launching into his tirade, "Because the mail never stops! It keeps coming and coming...and then it's Publishers' Clearing House day!"...ranting as he descends the ladder into madness.

ALSO: His courtroom cross-examination of Kramer about his speeding ticket, after Kramer traded him a defective radar detector.

Don't forget Newman after he stole Jerry's hair in "The Barber"

What about the scratching seen in "the Itch" !!!

I just saw a Newman scene the other night in The Barber that always cracks me up. It was when he was trying to help Enzo steal some of Jerry's hair and he comes to Jerry's door dancing on tippy-toes "Can I use your bathroom?"
