It’s time for a huge, freakin’ celebration because “Family Guy” is about to mark it’s 20th year on television. The animated sitcom centers around Peter Griffin (Seth MacFarlane), a fat and not-too-bright blue collar worker living in Quahog, Rhode Island. His family consists of Lois (Alex Borstein), his constantly ignored wife, Meg (Mila Kunis), their gloomy daughter, Chris (Seth Green), the dim-witted middle son, Stewie, a baby bent on world domination and matricide, and Brian, the intellectual and alcoholic family dog (the latter two also voiced by MacFarlane). We don’t have a random cutaway to help commemorate this anniversary, but we did put together the 40 greatest episodes of the series ever, ranked worst to best.
