I guess it's my favorite because I believe it';s the one I laughed the hardest - laughed my ass off. It was funny.
Kramer finds old Merv Griffin TV show furniture in a dumpster and puts it in his apt. and "fakes" a talk show with everyone who stops by. Meanwhile, Jerry's dating a girl with a huge vintage toy collection. And the only way Jerry, then with Elaine along, are able to even touch the precious collection, is to dope the girl so she sleeps while they play with the EZ Bake oven, G.I. Joe, etc.
Other than that, the stuck in the Hispanic parade traffic/George and the laser-pointer episode is hilarious.
I really miss that show.
