Corrected entry: In the scene where Detective Johnathan Stoppable is chauffeuring Police Chief Barkin around the World's Fair, they respond to a cry for help from Professor DeMentz. Upon arriving at DeMentz's exhibit, they find DeMentz lying prone on the ground. Chief Barkin and Detective Stoppable help him up off of the floor, and as they do, they spot Miriam "Mim" Possible running from the exhibit. Later in the show, we see Mim at the exhibit helping DeMentz off of the floor prior to his calling for/the arrival of Chief Barkin and Detective Stoppable. Mim then runs off after the thief who robbed DeMentz.
Corrected entry: Most of the gadgets Kim uses just couldn't work, simply for space reasons. For instance, the hair drier/ grappling hook couldn't work, because the hook is much larger than the opening it comes through. Also, all that rope couldn't fit inside that hair drier. The Kimmunicator has so many attachments that they couldn't possibly all fit inside it. In "A Stitch in Time Part One: Present" When Kim is going land surfing in Australia, the keychain-sized land surfers expand into regular sized land surfers, which just isn't possible. Mistakes like these run throughout the series.
Corrected entry: When Professor Chen says "It's college all over again, that man cannot build a robot" and professor Ramesh says "Yeah, he should take up cloning" and as seen in a later episode when Drakken makes Syntho-chemical duplicates that can be dissolved by soda, he can't do cloning right either.
Corrected entry: If you saw the movie, you know that Kim and Ron have done everything together since Preschool. If they had done everything together, Kim would have gone to Wannaweep with Ron, since it looked like he was in third grade, and she would have known about Gil's mutation way before this episode.
