The Burning - S9-E16
Corrected entry: When Puddy is sitting down and says "Feels like an Arby's night," he's leaning back with his arms outstretched across The Couch. When the show cuts to Elaine, Puddy suddenly has his hands in his lap.
The Slicer - S9-E7
Corrected entry: George's boss Kruger claims that the mole on his back hasn't changed in the past ten years from the picture on his desk. However the mole wouldn't be visible in the picture as you cannot see Kruger's back in the picture. Kruger is facing chest forward in the picture.
Correction: Kruger never says the mole is on his back.
Corrected entry: George asks Jerry for change because he doesn't have any singles and wants a Twix bar from the candy machine. The candy bar sticks, the mechanic gets it, and George still has no singles and no candy. How then did he manage to get 10 Twix bars for his "Candy Line up" that he wants to show the manager?
Corrected entry: The mechanic got the last two twix bars. Assuming George finally got change from the cashier, where did the twix bars come from for the candy lineup? And further, why wouldn't George just eat the twix since he wanted one so badly?
Correction: George presumably would have gotten the other Twix bars from a nearby store, off-screen. The reason why George didn't eat one of the Twix bars is simply all part of the joke - he was so determined and fixated on trying to catch out the mechanic that it simply did not occur to him that there were Twix bars there for him to eat. In fact, it is not until the plan had failed, where he then decides to have one if the Twix bars, only to find out there are none left.
The Frogger - S9-E18
Corrected entry: The Frogger Machine would have had to be, at some point, completely unpowered while switching it from the outlet to the battery.
Correction: No it wouldn't. As long as you connect some form of power to the machine's electrical source it could run on a battery. Think of appliances like iPods, alarm clocks, and hand-held video games. They can run on electricity directly but unplug them from an electrical point and they just switch to battery power if available.
Correction: When the shot switches to Elaine, Pussy still has his hands outstretched on The Couch just like the shot before. He slowly takes his arms off The Couch and puts them on his lap. There is no mistake in this scene.
