The best episode I've yet to see is "The Doodle." Here's why it's underrated.
You've got Newman and Kramer and their Mackinaw peaches.
You've got George and his "draped in velvet" thing (not to mention his lovely girlfriend Christa Miller).
You've got Jerry getting queasy about sharing a toothbrush.
You've got Elaine needing to get a synopsis of the Billy Mumphrey story from Kramer (great lines regarding the "simple country boy" and "cock-eyed optimist").
You've got George's complaining about how he'd rather have a woman think he's good looking and hate him.
You've got Elaine and Christa M. acting like school girls at the drawing class while discussing George.
You've got Jerry's parents trashing Elaine's hotel room.
You've got Kramer siccing the dog on Newman after Newman downs the last peach.
You've got Uncle Leo thinking Elaine was girl he ordered from the escort service.
Add to this fleas, fumagation, Chunky candy bars, and Kramer's temporary taste loss and it adds up to the best-written storyline ever!
My subjective opinion, mind you.
