Kim Possible

When the fish are dumped into the cockpit of the weather machine, Shego clearly says "So that's where the fish went." She should not have been able to say this while submerged in water, not to mention fish.

When Bonnie comes over Kim's house, the heart on Kim's shirt turns a different color for a moment (presumably mistaken for vacuum bag debris).

As Kim and Ron leave the Tri-City-Air booth, the bottom of Kim's hair turns green.

Janitor Joe was supposed to be Canadian, but he had an American accent.

When Ron releases the sneezing powder on Drakken, it goes in Drakken's face even though the wind was clearly blowing towards Ron.

Kim's hair gets wet from the rain while she and Ron are tied to the lightning rod. However, when she and Ron climb aboard Joe's floating ship, it appears to be fully dry.

Kirsten Storm's (Bonnie) name is misspelled "Kristen" in the credits. When Job Unfair aired on 8/29/03 at 10:30 Pacific Time, Kirsten Storms was spelled correctly.

During Kim's "OK girls, that was almost perfect" speech, one cheerleader's uniform is colored differently from the rest (gold bands rather than red). Stranger still, that same cheerleader's arm is missing from the wrist up!

That black that tops Shego's collar appears and disappears once again throughout the show. (I think the animators do that on purpose!)

While talking to Janitor Joe, Kim brandishes the Kimmunicator from her cheerleading uniform (pockets?)
