When Elaine is talking to Jerry about her missing her 4 o'clock sugar rush, the telephone cord switches from being under her arm to over.
When Jerry is talking to Elaine about thinking of breaking up with his girlfriend, Elaine is eating a cookie saying is the 4 o´clock dosis or whatever. Then Jerry says he will call his girlfriend to break up and Elaine tells him that those days are over and that he should go over to her place and break up with her in person. He says he´s afraid of the killer and Elaine says is still daylight.
When Jerry finishes breaking up with his girlfriend he asks "what time is it?" and she says "9". He then asks "We´ve been breaking up for 10 hours?". If so, he would´ve had to be there since 11 am, but it was around 4 pm when Elaine told him to go, so it´s inaccurate.
When Slippery Pete, Shlomo, and Kramer are standing outside playing Frogger, the sign behind them says "Mario's Pizza"; however, earlier in the episode, when George and Jerry went in for their last slice, the sign outside read "Fine Roses Pizza".
Though George's Frogger high score is stated to be 860,000 points, the verified world record as of 2005, 7 years after this episode aired, was actually still less than 600,000 points.
When Jerry and George walk into the pizza place you can see the stores across the street when the door is open. If you look closely you see that the sign on the cleaners is backwards, like you are looking at it in a mirror.
When Elaine calls Jerry from her office, we can hear her co-workers singing "Happy Birthday" in the background. A few minutes later Peterman catches Elaine in his office saying it was a "get-well party."
In the episode, it is mentioned that Mario's Pizza was Jerry and George's old high-school hangout.
George says that nobody's beaten him in ten years, when he sees the high-score still stands. In the episode "The Andrea Doria", George mentions he is 34. Which means the high score was achieved by him when he was 24. A bit old for high-school, isn't it?
If George had the highest score ever on that machine, how come he did not have any of the other top scores on the list. His initials "GLC" appears once in the top scores screen. Surely if he finished 1st he would have tried before hand and failed but would have at least made the other top spots.
When Jerry and George are watching the kid playing Frogger in Mario's, they cut to the game screen. . . where you can clearly see that the high score matches the current score of the kid playing: 7200 -- Georges score was 860,000. This wasn't posted on the screen until Jerry and George witness the score roster.
There are no versions of the old "Frogger" arcade game that kept initials. They only kept the Top 5 high scores and no initials.
(Shlomo and Slippery Pete are watching George cross the street like the frog in the game)
Shlomo: He looks like a frog.
Slippery Pete: So do you.
Jerry: (receiving an ugly new hat) Why don't you put it in the car so I don't accidentally toss it in that dumpster.
Elaine: Guess what I ate!
George: An ostrich burger?
Elaine: No, a $29,000 piece of cake. Peterman got it at the Duke and Duchess of Windsor auction. It's the most romantic thing I've ever eaten.
Jerry: How did it taste?
Elaine: A little stale.
Jerry: She's a sentence finisher. It's like dating Mad Libs.
George: Well, I'm doing it Jerry. I'm buying that Frogger machine. Now the torch will burn forever!
Jerry: Fabulous! See, now you're really doing something.
George: (on his gaming skills) Oh, I was unstoppable! Perfect combination of Mountain Dew and mozzarella, with just the right amount of grease on the joystick.
Elaine: (about her co-workers) I had to take a sick day, I'm so sick of these people.
George: Kramer, listen to me. I'm never going to have a child. If I lose this Frogger high score, that's it for me.
Kramer: Believe me George; you can count on Slippery Pete.
George: Slippery Pete?
Kramer: Yeah, I don't care for the name either.
Peterman: Elaine, can you keep a secret?
Elaine: No sir, I can't.
Elaine: Do you think we can fill the void in our lives with flour, sugar, eggs and vanilla? I mean, we're all unhappy; do we have to be fat too? (looks at Becky who is fat and is standing in the crowd) Not you Becky, I know you have a slow metabolism.
Elaine: Mr. Peterman, you wanted to see me, Sir?
Mr. Peterman: Elaine, up until a moment ago, I was convinced that I was on the receiving end of one of the oldest baker's grifts in the book: the Entenmanns's Shim Sham.
Mr. Peterman: Elaine, is the item still with you?
Elaine: As far as I know.
Mr. Peterman: Elaine, do you know what happens when a cake sits in a damp, poorly ventilated cellar for 60 years?
Elaine: (frightened) No.
Mr. Peterman: (letting her off the hook but smugly adds) Very well. I have the feeling what you're about to go through is punishment enough.
(Elaine stands there weakly.)
Mr. Peterman: (smugly tosses remote away) Dismissed.
Slippery Pete: What's that?
George: The outlet?
Slippery Pete: Mm-hmm.
George: That's where the electricity comes out.
Slippery Pete: Oh, you mean the holes.
Shlomo: Which one's the bathroom?
George: Uh, here.
Shlomo: They put the Frogger with the toilet? Yecchh.
George: The Frogger is here.
Kramer: George, I thought that was the door.
Slippery Pete: Where are all the pizza ovens?
Shlomo: I thought the bathroom was here.
Kramer: More bad news, Jerry. You know, the police - they found another victim of the Lopper in Riverside Park... I saw the photo, and it looked a lot like you!
Jerry: Oh, come on, there's a lot of people walking around the city that look like me!
Kramer: Not as many as there used to be!
Jerry: I think by sleeping with her I may have sent her the wrong message.
Elaine: (frightened) Get well, get well soon. We want you to get well! (in pain clapping) Get well, get well soon. We want you to get well!
Jerry: Hey George, how are you going to keep the machine plugged in?
Jerry: Well, when you unplug the machine, all the scores will be erased.
George: You're right. Why must there always be a problem. You'd think just once I'd catch a break. God knows I earned it with that score.
Jerry: You sure do have a lot of friends, how come I never see any of these people?
Kramer: They want to know why they never see you.
Lubeck: It's an Entenmann's.
Peterman: (with vain hope) Do they have a castle at Windsor?
Lubeck: No, they have a display case at the end of the aisle.
George: Hey, Jerry, remember Frogger? I used to be so into this game. Getting that frog across the street was my entire life.
Jerry: Yeah, and then you went on to... well, it's a good game.
(Frogger gets hit by truck)
Jerry: Game over.
