For me, these episodes, and several that were broadcast before and after it, were the funniest in the season's history. This episode in particular was very well written, with the gags coming fast and furious for the most part. What is even more impressive is the delivery by all the actors in this episode. They were spot on and had the perfect tone and presence to pull it off.
I also like the fact that there were multiple actors in this episode. Even through most of the characters are background, the writers utilized a dermatologist for two very funny gags. How often do you see that on a network comedy?
One of my all time favorites.
