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.
Wow, now I see why they call you Miss Hoover. You must have been vacuuming for an hour.Bart
Bart: I call first bedsies!
Lisa: Bart, there's no such thing as first bedsies. You just made that up.
Bart: Well, okay. Which one do you want?
Lisa: I ... want ... that one.
Bart: Really? You want that one? Well, it's all yours, whatever you say.
Lisa: Why, what's wrong with it?
Bart: Nothing! Have a good night's sleep, Lisa.
Lisa: No, really, what?!
Lisa: What did you do to it?
