Continuity mistake: When Kim and Shego stop chasing Ron back in Drakken's lab Shego is wearing a purple apron, then the camera moves away Shego and Kim then comes back and Shego is not wearing a purple apron, then the camera moves away again and then comes back to her and now she is wearing the apron.
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.
