19. I Am Not A 32 Year Old Woman (Season 2, Episode 6 - Dead Putting Society)
Of course Bart isn't a 32 year old woman, right? Why would he need to be told that? This is a reference to the fact that his voice actress, Nancy Cartwright, was 32 years old at the time this episode aired, as well as the fact that a lot of casual Simpsons fans aren't aware (or rather, weren't aware at the time) that the character was voiced by a woman.
