This never gets old...Cameron Crowe=Genius

Mr. Hand: Where is Jeff Spicoli? I saw him earlier today, near the first floor bathrooms, is he still on campus? Anyone?
[Desmond raises hand]
Mr. Hand: Yes, Desmond?
Desmond: I saw him outside, near the food machines.
Mr. Hand: How long ago?
Desmond: Right before class.
Mr. Hand: Alright. Bring him in.
[Desmond exits]
Mr. Hand: What is this fascination with truancy? What is it that gets inside of your heads? There are some teachers at this school who look the other way at truants. It's a little game you both play. They pretend they don't see you, and you pretend you don't ditch! Now, in the end, who pays the price? YOU!
[Desmond re-enters; Spicoli follows him. He has a bagel stuffed into crotch; with open shirt, barefoot, holding Vans]
Jeff Spicoli: [Desmond re-enters; Spicoli follows with bagel stuffed into crotch; with open shirt, barefoot, holding Vans] Wait a minute, there's no birthday party for me here! Hello, Mr. Hand.
Mr. Hand: What's the reason for your truancy?
Jeff Spicoli: Just couldn't make it on time.
Mr. Hand: You couldn't, or you wouldn't?
Jeff Spicoli: See, there was a full crowd at the food lines.
Mr. Hand: Food will be eaten on YOUR time. Why are you continuously late for this class, Mr. Spicoli? Why do you shamelessly waste my time like this?
Jeff Spicoli: [long pause, but then with complete truth in his answer] I don't know.
Mr. Hand: [Mr. Hand goes to blackboard and writes the words 'I Don't Know', then underlines them]
[reciting]
Mr. Hand: I like that. 'I Don't Know.' That's nice.
[imitating]
Mr. Hand: 'Mr. Hand, will I pass this class?' Gee, Mr. Spicoli, I don't know! You know what I'm going to do? I'm going to leave your words right up here for all my classes to enjoy, giving you full credit of course, Mr. Spicoli.
Jeff Spicoli: Alright!
