Roger is shown to put on his suit jacket twice. Once for when Kenan tells everybody that he would want to surprise everyone for giving a speech. The other time is when Kyra asks why Kenan and Kel have different colors of graduation gowns.
When Kenan runs back to his seat, Roger's arms are up in the air. In the next shot, they are not.
The contrast of pudding on Miss Horn's face and how deep the pudding is in her hair changes between shots when she bans Kenan from the graduation ceremony.
After Kenan stands up, the pudding on the wall is on the left of the door when entering. Two shots later, the pudding is on the opposite side of the door and the background outside changes. After Principal Horn tells than Kenan to go, it goes back to the way it originally was earlier.
We never see Chris go by Kenan on the right side of the table to the left at the restaurant scene. After Kel says that Kenan was under the table, where Chris was at the first, the next shot shows his right sleeve when he is on the left.
If you look closely, both Kenan and Kel's cap have a tassel with the number 99, meaning they will graduate in 1999. At the graduation scene, there is a banner that says, "Congratulations Class of 2000", stating they graduate the next year.
A backdrop can be seen behind the graduation stage.
After Kel comes out from the bulldozer, he tosses his cap into the air. Behind the stage, another cap is thrown into the air and is shown as well as the cap going down to the ground, as if Kel tossed that cap.
Palm trees can be seen when Kel brings in the bulldozer.
Chris states that Kenan took many boxes of pudding yesterday. However, this occurred earlier due to the fact that Kenan and Kel were wearing the same clothes in both scenes.
