Christa Miller-Lawrence who appears in this episode as Elaine's artist friend Paula, appeared as Ellen de Granmont (the woman whose material George feels) in last season's "The Sniffing Accountant". She can currently be seen as regular character Ellie Torres in Courtney Cox's new series Cougar Town.
From this episode on; Uncle Leo is a very minor character.
When Elaine goes in Jerry's apartment for the second time, you can see a bright light in the door crack. When she gets in, there is no lights on.
While Kramer is eating the Mackinaw peach the amount eaten varies between shots
Christa Miller (of Drew Carey fame) played a different character in the Sniffing Accountant. She was the woman who worked at the bra selling company and when George felt the material on her shirt she got angry with him. In that episode her name was Ellen.
In this episode her name is Paula, and she's even dating George!
Elaine blesses herself before she enters Jerry's apartment while it's being fumigated. She reveals in The Burning that she is an Atheist.
Paula: (to George) You could drape yourself in velvet for all I care.
Newman: (to Jerry) So you have fleas. Maybe you keep your house in a state of disrepair. Maybe you live in squalor.
Elaine: The point, George, is she likes you.
George: Oh, so what. I'd rather she hate me and thought I was good looking.
Jerry: See, the thing of it is, there's a lot of ugly people out there walking around but they don't know they're ugly because nobody actually tells them.
Jerry: (about George) When he's dead he'll be relieved.
Kramer: I used to have fleas.
Jerry: What did you do about them?
Kramer: What do you mean?
Kramer: (eating Mackinaw peaches) It's like having a circus in my mouth.
George: I want you to find out if she likes me.
Elaine: Find out if she likes you? What, are you in high school?
Jerry: Oh man, did you see that? I ate discarded food!
George: Well, I've done that.
Jerry: Yeah, but with you it's intentional.
George: You know Jerry; I've been searching for someone a long time. Well, the search is over.
Jerry: And now the search for the right psychiatrist begins.
Leo: (sees Elaine) They said they were sending an Asian woman.
George: I suppose we could go to Lincoln Center and I'd be wearing sneakers and jeans and that would be fine, too.
Paula: You can wear sweatpants.
George: (stunned) I could?
Jerry: (sniffs wrappers) I know the chunky that left these Chunkies... Newman!!
Jerry: Mom, Dad… I have fleas!
In a deleted scene on the Season 6 DVD, we learn that Buford, the bulldog that chases Newman in the final scene, is the dog that gave him fleas in the first place.
Viewer Daniel Massey notes that Newman's apartment in this episode is 5F.
When George wears the velvet outfit, Jerry refers to him as the "Velvet Fog". This is a nickname for Mel Torme, who incidentally, was featured in the previous episode ("The Jimmy").
Paula: You can drape yourself in velvet for all I care.
This alludes to George's dream, as mentioned in several episodes throughout the series; that were it socially acceptable he would drape himself in velvet.
