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.
