When Jerry is racing Duncan at the end of the episode and everyone starts cheering, there is a scene where Elaine is cheering for Jerry, there is a close up of Elaine and the people around her are very different from those standing around her in the far shot. In fact the scene appears to also have been re-used in the "Little Jerry" episode as well. Given the timeline this was probably filmed and then reused the "Little Jerry".
Elaine's address is 16 W. 75th St., #2-G.
The original airdate, December 15, 1994, was 16 years to the day after the general release date for Superman: The Movie (Dec. 15, 1978) whose theme music is featured in the climactic race scene.
On this episode, Mark Christopher Lawrence plays Kramer's boss. In "The Airport", he played the luggage valet working at the airport when Jerry and Elaine ask him how much they should give him for tip.
When the man for Hop Sings is on the phone talking to Elaine, you can see behind him a sign that says "Do not deliver list".
When Jerry tells Elaine about the race in her apartment, Elaine puts her glass on the front edge of the coffee-table. In the next shot it is far on the other side of the table - pure magic!
George is excited about the prospect of a woman for whom appearance is not important, but in "The Doodle" George is offended that the woman he is dating says the looks are not important.
The outside of George's office is very different from that we see in other episodes. In this one we can see the sits in angle, but in the rests of episodes the sits are more hidden and the court is pretty more visible.
Elaine claims that Ned reads the Communist newspaper "The Daily Worker"...however, The Daily Worker ended publication in 1957, during the "Reds Under The Bed" sweep of American Communism, led by U.S. Senator Joe McCarthy. So, unless Ned is reading a 35+ year old paper, than that can't be The Daily Worker.
Kramer: There are no delicatessens under communism.
Mickey: Whoa! Why not?
Kramer: Well, because the meats are divided into a class system. You've got pastrami and corned beef in one class and salami and bologna in another. That's not right.
Elaine: (to her boyfriend) Fine, you want to be a communist, be a communist. Can't you at least look like a successful communist?
Kramer: (working as a department store Santa Claus) Eight hours of jingle-belling and ho-ho-hoing. Boy, I am ho'd out.
George: (trying to get a date with a communist) Yes, this is a business office, but I'm not a businessman per se. I'm here working for the people. I'm causing dissent, stirring the pot, getting people to question the whole rotten system.
George: I can't believe you're really going out with a woman named Lois.
Jerry: I know. Finally!
Lew: I knew it was you! You tried to trick Hop Sing! You are on our list; Elaine Benes! And now you are on our list; Ned Isakoff.
Ned: You got me blacklisted from Hop Sing's?!
Lew: She named name!
Elaine: Just because you're a Communist, does that mean you can't wear anything nice? You look like Trotsky.
George: (about personal ad) It says appearance not important!
Jerry: Yours or hers?
Jerry: I didn't hit puberty until the 9th grade…that's what gave me my speed.
Lois: So you were the fastest kid in school?
Jerry: Faster than a speeding bullet, Lois.
George: (about communist personal ad) 'Appearance not important!' This is unbelievable. Finally, this is an ideology I can embrace!
Jerry: Why, I'd have to be Superman to do that, Lois.
Elaine: Ned's very well read.
George: Or, maybe he's just very well...red.
Kid: Santa's a commie!
Mickey: How did a kid like you learn such a bad word like that?
George: So what have you been doing with yourself?
Jerry: I'm a comedian.
George: So what do you do, a lot of that "did you ever notice," this kind of stuff?
Jerry: Yeah, yeah.
George: It strikes me a lot of guys are doing that kind of humor now.
Jerry: Yeah, yeah. Well, you really got bald there, didn't you?
Elaine: Well, I'm dating a communist!
Jerry: I choose not to run!

Elaine: (to Ned) Just because you're a communist, does that mean you can't wear anything nice? You look like Trotsky.
Leon Trotsky was a one of the leaders of the Russian revolution and went on to become one of the first members of Russia's communist governing body. He was a firm believer in the ideas of Karl Marx, who created many of the basic ideas in modern communism.
When the child that can't speak English approaches Kramer (as Santa) and he pretends to respond in her language (really gibberish), it alludes to the 1947 film Miracle on 34th Street in which Edmund Gwenn as Kris Kringle responds to a little Dutch girl in her own language.
The Chinese food delivery man's insistence that Elaine give him a name to go with the order is a reference to America's "Red Scare" and subsequent hunt for/prosecution of communists.
Many lines throughout the episode, such as "Faster than a speeding bullet, Lois," "Jimmy's in trouble, Lois," "Why, I'd have to be Superman to do that, Lois," and several others are clear references to Jerry's favorite comic book character, Superman. The entire Jerry/Duncan race plotline, including the music, includes many references to Superman comic books, the Superman TV series starring George Reeves, and the Superman movies, starring Christopher Reeve.
Jerry: "I choose not to run."
The only reason Calvin Coolidge gave for not running for president of the United States was: "I choose not to run for President in 1928."
