In the first day of school, Stoner Bud (Eric Stoltz) puts his skateboard on his locker but when the bell rang he was still holding his skateboard when they get off the van.
Oops! After Brad gets fired & punches the bathroom door, the sound doesn't come until after he has punched it.

Spicoli's pizza is supposed to be extra cheese & sausage but when the pizza's shown, there's clearly no sausage!
Mr. Hand was wrong about the Platt Amendment! He tells his class that the Platt Amendment was "a piece of legislation introduced into Congress by Senator John Platt. It was passed in 1906. This amendment to our Constitution has a profound impact upon all of our daily ..." (He stops because he notices that Spicoli is absent.) The senator's name was Orville H. Platt, not John.
The legislation was introduced in 1901. The Platt Amendment was not an amendment to the U.S. Constitution, but, rather, to the Cuban Constitution. (It's major impact was to keep European nations away from Cuba and it led to the establishment of Guantanamo Bay.)

In the scene were Jeff Spicolli has to be brought to class by a fellow classmate (the scene when he comes in with the bagel in his pants) there is a blooper with the clothing on the boy in the front row.
When Mr. Hand is writing the famous "I Don't Know" on the board, it shows the class reaction as he is writing it. Take note of the boy on the left hand side of the screen in the front row, they first show him with his vest off. Then they show him again and the vest is clearly on. You may reconize this boy, because he played one of the geeks in John Hughes' "16 Candles."
Amy writes in with an update: The entire scene where Mr. Hand writes "I don't know" on the board has clothing issues. Stacy is seen from behind wearing what appears to be a brownish sweater, but from the front she has a pink shirt and red vest. The boy on the right in the front row has a green and white baseball shirt, but in the earlier scene from behind he is wearing a light colored collared shirt. As I am watching it on DVD, I just noticed something. The front view of the class in the "I don't know" scene is the same as the one in the pizza delivery scene (with the addition of Spicoli in the latter).
The ticket booth at the theater where Ratner works has a sign that reads, "No smoking or food inside" but when Ratner is greeting guests, you can hear him say repeatedly, "Smoking is upstairs to your left."
