Friend of Aly and Melanie: She was totally edging on my squeeze, so I dinged her with a bounce-bounce in the numbers lab.
Jean: You have to worry.
Michel: He means to say: you don't have to worry.
Barbara Porter: Look, I know your grandpa's not great with you girls.
Melanie 'Mel' Porter: Mom, that's like saying the Titanic's not great with icebergs.
Other mistake: When Mary-Kate and Ashley arrive at the dance, the two boys are up on stage with their band. They are both playing the guitar, but when they see the twins they put down the guitars and go to see the girls. The thing is that the music sounds exactly the same before they leave as after they leave.
