Character mistake: When Olivia turns up at Jackson's house, she says, "That was my Saturday afternoon. This is my Saturday night!" which indicates it is the same day. But when Cooper arrives, he says, "Sorry for blowing off at you yesterday," which means another day has passed. However, at the Hannah concert, it is the same day all the while, so Cooper had got his days wrong.
Oliver: You have an extra ticket to Hannah Montana!? [everyone in lunchroom gasps.] That was really loud, wasn't it?
Trivia: In the episode where Lilly and Luke are going out, a man and his two daughters are waiting for a table. Hannah comes in and gets a table. The man says, "Why didn't we get in?" One of the daughters says, "Face it, Dad. She's bigger than you." The other daughter says,"Well, he is one of the makers of the show Seinfeld." Then the other one says, "Yeah, we could get in if Uncle Jerry were here." She is referring to Jerry Seinfeld.
