That's So Raven Season 1 Episode 21

Why would students need to exit the gym and walk down an additional hallway to get to the locker rooms? Most school's have the locker rooms connected to the gym or close by (in the same hallway).

During the "lip gloss" scene on the wall between Raven and Chelsea, doubles were used for Raven and Chelsea. You could tell because Chelsea's double has bigger hands, and Raven's double has bigger, darker, and manish hands. Also, Raven has nail polish on, but her double doesn't.

This is the last episode of Cory having a crush on Chelsea.

When Cory and Viv are playing with the lasers, there is no furniture in the living room. But when they are finished the furniture is back.

When Chelsea is first walking down the Jock Block and turns around you can see that the toilet seat cover is squarish and tucked into her belt but when they cut away and cut back it's a different seat cover thats the oval seat shape and instead of being tucked in it's actually stuck to her skirt.

In the kitchen when Viv scared Cory with the head on the platter she was saying "Bring it on little man..." and you can see Chelsea peeking from behind wearing her jacket, they cut away and cut back real quick from a different point of view and Chelsea is no longer wearing her jacket.
