Homer Jay Simpson is the bumbling husband of Marge, and father to Bart, Lisa and Maggie Simpson. He is the son of Mona and Abraham "Grampa" Simpson. Homer held over 188 different jobs in the first 400 episodes of "The Simpsons". In most episodes, he works as the nuclear safety inspector at the Springfield Nuclear Power Plant, a position which, whilst being wholly unsuitable for, he has held since "Homer's Odyssey", the third episode of the series. At the nuclear plant, Homer is often ignored and completely forgotten by his boss Mr. Burns, and he constantly falls asleep and neglects his duties. Matt Groening has stated that he decided to have Homer work at the power plant because of the potential for Homer to wreak severe havoc. Each of his other jobs has lasted only one episode. In the first half of the series, the writers developed an explanation about how he got fired from the plant and was then rehired in every episode. In later episodes, he often began a new job on impulse, without any mention of his regular employment.
