The Princess Diaries (2001)

Continuity mistake: Just before Mia goes to smash her ice cream cone into Lana's chest, she takes a bite off the top of the ice cream. When she pushes it towards the camera, you can see that it hasn't been eaten at all.

Mia: Somebody sat on me again.

Trivia: In the scene where Mia slips and falls on the bleachers, Anne Hathaway actually did fall. The director thought it was so funny that he decided to leave it in there. Notice how Mia and Lilly fall out of character and start laughing, but in the next shot they're immediately serious again as if nothing happened.

Question: Mia asks Joe in the limo if they can "86 the flags." Obviously this means get rid of, but what is the origin of "86?"
