In the world of adult cartoons, few shows have had the same impact as Family Guy. This less-than-typical family is outrageous and funny to the extreme. The show has been going strong since 1999, and clocks in on over 300 episodes, with no signs of slowing down. Of course, fans everywhere couldn't be happier about this, and there's a big chance Family Guy will keep us laughing for many years to come. There are a lot of factors that contribute to the series' popularity, but one of the biggest ones is, undoubtedly, the eccentric character of Stewie Griffin.
