When Kramer is staying at Jerry's apartment because his keys are at the Jiffy Park, he wants to go to bed early and Jerry is upset because he doesn't want to go to bed yet. After a little bit of arguing, Jerry asks him why he doesn't go sleep at Newmans' and Kramer says because he's "up there with a girl". Newman lives on the same floor as them in apartment 5C.
Jerry says that he's interested in buying a crested blazer because he "once wore one" and liked it. It seems odd that he'd refer to his wearing the jacket as "once", considering that it was in the last episode ("The Friars Club").
Why Kramer says he doest fit in Jerry's couch?, We know the couch is also a bed when Jerry's parents stayed at his place before, so why didnt just Kramer open the couch and turn it into a bed?
George seems to have had a change of heart since "The Parking Space", where he proclaims that he can never bring himself to parking in a lot, because "parking in a lot is like going to a prostitute, why pay for it, when if i apply myself i can get it for free." But seems very enthusastic about parking in the Jiffy Park lot.
Jerry: I'm telling you right now, Elaine, this guy's gonna dangle that dress in front of you like a dirt farmer dangles a carrot in front of a mule.
Elaine: Well, this is all very flattering…
Jerry: Like a shark fisherman with a bucket of chum.
Jerry: Like a shrimp farmer…
Jerry: I'd like to return this jacket.
Clerk: Certainly. May I ask why?
Jerry: For spite.
The police officer at the last scene is the voice of Larry David, "I said turn pimp!".
At the "Jiffy park," the man working tells Kramer that if he has a problem to take it up with Consumer Affairs, and after talking with the man at the "Jiffy dump" Kramer is seen yelling "maybe I will take it up with Consumer Affairs!"
In episode 155 "The Muffin Tops" the name from the parking lot "Jiffy park" returns, but this time it´s a dump called "Jiffy dump" where Kramer wants to dump Elaines garbage from the Muffin top store. Also note that it´s the same man who´s working at the dump as on the parking lot.
Susan catches George paying a prostitute. In the episode The Postponement (112) the rabbi Elaine confided to said on his show that George had been wondering whether it was cheating if he'd pay a prostitute to have sex with him.
Kramer's mug shot number is NYPD 331781-0404.
