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.

Edna: Bart, is it a walking clock?
Bart: What?.....No, it's my dog.
