Welcome to WatchMojo and today we’re counting down our picks for the Top 10 Mistakes in The Simpsons That Made It to Air. For this list, we’ll be looking at goofs with animation, voices, and continuity that made it to the final cut of "Simpsons" episodes.

Over the course of hundreds of episodes, there are bound to be a few contradictions. Welcome to WatchMojo.com, and today we’re counting down the Top 10 Plot Holes in “The Simpsons” That You Probably Never Noticed. For this list, we’re looking at plot holes, inconsistencies, or unexplained occurrences that have happened throughout the long-running animated sitcom. However, we won’t be including “Treehouse of Horror” episodes or “The Simpsons Movie,” nor will we be including anything that’s intentionally inconsistent, such as the location of Springfield or Mr. Burns’ age. We’re also not saying that these plot holes make the episodes or series bad, but that they just plain don’t make sense.
