Bartholomew "Bart" Simpson is voiced by Nancy Cartwright (that's right, a woman!) and is Homer and Marge's only son on The Simpsons.  Bart is an underachiever and was definitely much more of a bad boy in th ebeginning seasons of the show.

Now, Bart, although he has not aged, has certainly matured as a character.  Do the Bartman people.

Dearest Edna, I must leave you. Why, I cannot say. Where, you cannot know. How I will get there, I haven't decided yet. But one thing I can tell you, any time I hear the wind blow it will whisper the name Edna. And so let us part with a love that will echo through the ages. ---Woodrow
