Launch Party - S4-E3
Other mistake: In the beginning of the episode Meredith asks Jim to sign her cast. If you look closely, it's obvious that the actor John Krasinski signs his real name, not the name of his character, Jim Halpert. (00:02:35)
Other mistake: When Marshall returns from Minnesota, he approaches Lily lying on the couch from the kitchen area rather than from the door, and Lily still acts surprised to see him, even when he was obviously already in the apartment with her.
Other mistake: In the opening of this episode the screen reads "3:50pm On a Wednesday." When Gino (Frank's Brother) is reading the letters meant for Shadynasty, he says "Meet me at the airport, Friday, at 5:00, Terminal C." The gang and Gina then go along to the airport that very afternoon - a Wednesday - to try and meet Shadynasty and get her and Frank back together. And of course she is there, despite it being a Wednesday, not a Friday.
Other mistake: It appears as if Steve is holding 3 $20 bills when he supposedly received $50.
The Lion Sleeps Tonight - S8-E18
Other mistake: At the beginning of the episode, when Meredith, Derek and Zola see the lion crossing the street in front of the car, the lion roars and it is clear that the lion is not missing any teeth. However, later in the episode, Richard removes a tooth that had gotten lodged in the male mauling victim's arm. The victim was the lion's owner and the attack happened in his house, so by the time the lion was out the tooth should already be missing.
It's a Mad, Mad, Mad Hotel - S1-E12
Other mistake: In the episode "Its a Mad, Mad, Mad Hotel", when Esteban has his dream of becoming rich and London becoming his "Bell Girl", he calls the hotel "Hotel Esteban, but London's uniform still has a "T." When it cuts there is an "E" on the front desk.
Other mistake: When Stacy sees Zoey's designed backpacks for the first time, she uses her camera to take pictures of them. In one shot, a close up of the camera display is shown and the message "CF card full" is on the display and yet the camera still makes "click" sounds as Stacy seems to take pictures. (00:10:22)
Other mistake: When Andy pulls his piece of meat out of the fondue pot it hasn't been cooked at all. The fondue obviously hasn't been turned on (in the next shot he sticks some meat in his mouth, which has been cooked and is smaller).
Gopherville - S1-E1
Other mistake: In "Sock Safari", when Toopy finds a red thread, his left hand with his glove disappears instantly.
Other mistake: When Earl meets with Kimmi in her room, she's supposed to watch "You've Got Mail" - her TV, however, is switched off.
