Gilmore Girls

While she's looking at Jackson and Sookie having their first date, Lorelai tells Luke that she'll wear blue at their wedding. In "I Can't Get Started" (season 2), the episode where Sookie and Jackson get married, she actually wears blue.

When Lorelai tells Rory how she shouldn't have lied to her, she says, "I have to know where you are at all times". She did know where Rory was - she was at the movies which was exactly what she'd told Lorelai where she'd be. The only thing Lorelai didn't know was that Todd was there, too.

While waiting in line for the movie, Lane asks Todd what he wants to major in. He responds that if he majors in gym, he only has to take three classes senior year. This implies he is currently in the school where he will be majoring, if he already knows how the courses will be scheduled. However, he, Dean, and Lane are students at Stars Hollow High. High school students do not have majors.
Possible explanation: Many high schools do actually have tracks and call them "majors": "business" students often are on a special track and take classes primarily to help them become employed after high school if they're not planning to go to college (typing, computer science, business, economics in my day). Other students are on an AP track.

When Lorelai and Sookie answer the door to Jackson and Rune, you can see an office building window behind Jackson and Rune.

Lorelai told Mrs. Kim that the girls went to a movie with Dean. They did go to the movies so that was not a lie, but Rory and Lorelai kept talking about how Rory lied. The only thing that Lorelai didn't know was that Mrs. Kim didn't know about it. She also says that she would not have lied for Lane even if Rory had told her the truth because one mother can not lie to another, it is the parents code. This,however will be the only time Lorelai cares about this so-called code. Multiple times in the future, Lorelai will do the opposite where Lane is concerned (encouraging Lane to tell her mother something else when they have Bangles tickets, allowing her to hold band rehearsals in her garage, holding onto Lane's purple hair photo,etc) Lorelai only cares about lying directly to Mrs. Kim because Mrs. Kim "scares her."

At the start of the show, Lane tells Rory she wants Dean to talk to Todd to set up a date. However, when they're on their date, Lane finds out that Todd is actually pretty dumb. In "Kiss and Tell" we learn that Lane already spoke to Todd on a previous occasion and thus would already know that Todd wasn't one of the brightest.
