Busboy. Second perfect episode, IMHO. Raises the bar very high for future episodes. Two amazing scenes dominate the episode: George & Kramer in the busboy’s apartment, and Elaine’s frantic attempt to get her house guest dressed and out the door. Not just hilariously funny, these scenes are beautiful to watch. And rewatch (I watched the episode twice back-to-back). Jerry has no storyline in this one, and appears only in a support capacity. The other three carry it. And it is superb. Just a joy to behold. 10/10
