We Got Us a Pippi Virgin - S5-E5
Continuity mistake: When they are starting Pippi and Luke is asking about her hair, you can see Dean's hand on Rory's shoulder on the side of the shot. Then it pans to them and then Dean is putting his arm around Rory.
Continuity mistake: In this episode, when Logan goes to see Lorelai to ask her permission to propose to Rory, Lorelai asks Logan if he wants any french fries. They sit down and the to-go container is open, when the camera zooms in and then back out it's closed again.
Visible crew/equipment: When Lorelai joins Rory at Luke's, as she opens the door, she reveals camera equipment outside the door. (00:20:00)
Suggested correction: It's not camera equipment you're seeing; it's one of the newspaper dispensers on the sidewalk outside Luke's, at the curb. These newspaper dispensers are visible in many episodes.
Dear Emily and Richard - S3-E13
Character mistake: Lorelai calls Rory "Suki" when they are unboxing the books Emily gave to them. (00:10:08 - 00:31:11)
Suggested correction: She calls her "sweetie."
Twenty-One Is the Loneliest Number - S6-E7
Other mistake: Though I love the 21st birthday at the casino plan, it's flawed. Rory will not be able to play blackjack until she is 21. She can't be playing when she turns 21. Casinos, to the best of my knowledge, won't let you on the gaming floor unless you are 21. She has to turn 21 first.
The Big One - S3-E16
Other mistake: Headmaster Charleston called Rory to discuss the speech contest. His secretary conferenced in Paris. When Headmaster Charleston hung up, the connection between Rory and Paris should have been severed. They were both connected to him, not to each other.
Twenty-One Is the Loneliest Number - S6-E7
Other mistake: After Emily goes to the pool house on the pretence of looking for a blouse, she asks Logan about plans for Rory's birthday. Later, Emily and Richard talk. Emily suspects that Rory is ready to have relations with Logan. She says that she caught them getting cozy on the couch. Emily didn't catch them doing anything. There was no way for Emily to see inside. Both Logan and Rory got off the sofa to answer the door. Emily didn't see anything. And, Logan told Emily that he had no plans for where his birthday. He knows that Emily is planning a party, yet he offered to take Rory away for her birthday. Emily would've been devastated.
Other mistake: Lorelai is in bed post breakup. Rory returns from running errands for her. She comes upstairs with Frank who is carrying the television. Frank puts down the television and leaves. When Rory leaves, Lorelei turns on the TV. No one plugged it in or hooked up the cable, assuming that cable is installed in her bedroom (which is extremely doubtful). Lorelai would not have been able to flip through channels as she did.
Character mistake: While Rory is on the phone discussing a DAR application, Emily enters. Rory asks the caller to hold, but she doesn't hit a button to put the call on hold. She put down the receiver disconnecting the call. Then she forgets that she has someone on hold.
Women of Questionable Morals - S5-E11
Other mistake: When Rory goes to see her father after Strobe dies, she brings a paper bag with cookies. Christopher comments "and milk", even though the bag was creased. He couldn't see into the bag because the bag is closed.
Other mistake: Lorelei, Rory, and Luke are about to leave for Emily and Richard's wedding. Babette is on the sofa half passed out from the bachelorette party. When she hears Lorelei speak her name her head pops up to say goodbye, and she also comments that Luke looks nice. Luke is wearing a long overcoat. She could not possibly see how he looks, plus she was viewing him from behind.
Like Mother, Like Daughter - S2-E7
Continuity mistake: When Mr. Charleston is looking at Lorelei's parent file, he closes it and starts talking and in the next shot he is seen closing it again.
Rory's Birthday Parties - S1-E6
Continuity mistake: Rory's piece of birthday coffee cake changes sizes throughout the whole scene.
Star-Crossed Lovers and Other Strangers - S1-E16
Visible crew/equipment: While Patty and Taylor argue about the fire and Stars Hollow, there's a mic dip over Lorelai's head right before Luke says "she's bi-polar. And again when Patty says "she is?" (00:13:25)
