Bart Simpson [SEP] Introduction
Bartholomew JoJo Simpson is a fictional character in the American animated television series "The Simpsons" and part of the Simpson family. He is voiced by Nancy Cartwright and first appeared on television in "The Tracey Ullman Show" short "Good Night" on April 19, 1987. Cartoonist Matt Groening created and designed Bart while waiting in the lobby of James L. Brooks' office. Groening had been called to pitch a series of shorts based on his comic strip, "Life in Hell", but instead decided to create a new set of characters. While the rest of the characters were named after Groening's family members, Bart's name is an anagram of the word "brat".
