Corrected entry: Why does Frenchie have a TV in her bedroom? Only really rich people had multiple televisions in the 1950's. (00:25:05)

Correction: Perhaps Frenchy had moved the main TV from the living room into her bedroom.

Corrected entry: In the dance scene at the school, Doody can't dance with Frenchy and apparently Jan has trouble dancing as well, but later on nobody seems to be having any trouble dancing.

Correction: Jan can dance. The problem Putzy has is that Jan wants to lead all the time.

Corrected entry: Rydell manages to have cheerleading tryouts and student council elections in the first few days in the fall of their senior year. No high school does that. Both of those activities are done in the last few weeks of the students' junior year to allow for cheer camp and such.

Correction: Grease was supposed to be taking place in the 1950's, I'm sure cheerleaders did not start attending Cheer Camps until the 80's or 90's.

Corrected entry: The first day of school the Principal invites everyone to the pep rally coming up. After the Pep rally that week all the Pink Ladies and Sandy go to Frenchie's for a party. At this party is when Rizzo leaves and her and Kenickie have their "accident." Yet Rizzo doesn't find out until the carnival at the end of the school year that she's not pregnant. That would have been one heck of a first trimester...

Correction: It is safe to assume that Rizzo and Kenickie had been dating throughout the entire school year.

Corrected entry: In the end during "We Go Together", there is a scene where Sandy jumps towards Danny and she doesn't have her red Candies shoes on.

Correction: She's holding them in her hands.

Revealing mistake: In the soda shop, the waitress turns off the lights with her elbow because her hands are full, but she misses the light switch by 6 inches. (00:55:10)

Rizzo: I got so many hickeys, people'll think I'm a leper.
