I like the parking garage one too. I also like the Handicap Space. And the episode were Elaine and Jerry are trying to buy chocolate babka and Kramer and George are trying to get the wine. Very funny episode
I also like the backwards wedding. Some of my other favorites are:
The Contest
Serenity Now
The Abstinence (George becoming smart, while Elaine became dumb was too funny)
Yada Yada Yada
Loved the episode (don't know the name) when Jerry dated the girl who wore the black & white dress all the time.
The Episode when George experiences "significant shrinkage"
The Episode when Elaine told Jerry that she "faked it"
