Continuity mistake: Right after the cheer off, there's a wide shot of Kim and Ron. As Ron is saying, "Uh, yeah about that," he moves into a shadowed area (look at the lockers). It cuts to a close-up as he says his line, and he's still entering the shadowed area.
Continuity mistake: In the episode where the villain is in Smarty Mart (forgive me, I forgot the name of the episode), Wade has a cup beside him. Then he smashes the cup. The shot switches to Kim. The next shot of Wade, the cup is back to normal, and he takes a drink out of it.
Other mistake: After Ron pulls the monkey hair for Wade to analyze, Wade says something about placing it on the scanner. Then a tray comes horizontally out of the top of the Kimmunicator. The tray is about two and a half inches long, and the Kimmunicator is about half an inch thick. The tray is too big to fit in the Kimmunicator's top.

Continuity mistake: After Ron writes the answer to the math problem on the board, writing appears and disappears below his answer between shots.
