Family Guy hits 100 tonight.

Sunday's episode, "Stewie Kills Lois," will be preceded by the Family Guy 100th Episode Special, a half-hour clip fest to remind fans of some of the Griffins' most outrageous moments, which have become decidedly more outrageous, more nonsensical and, subsequently, more polarizing—you're either cracking up or calling the Parents Television Council—over the past two years.

In fact, just this week the PTC named Family Guy the worst show for young audiences, which along with MacFarlane's other Fox show, American Dad, puts "irreverence on parade on a weekly basis while relentlessly breaking taboos with sexual content and cartoon violence."

But, as it is with many shows that are at times uncomfortable to watch (such as It's Always Sunny in Philadelphia, The Office, The Simpsons and South Park, to name a few), it's the envelope-pushing that comes to make it different and makes it a resilient fan favorite.
