Oh, my God, they killed Brian! You b*****ds!

On Sunday night, "Family Guy" did the unthinkable (even for them). The Griffins' beloved family dog, Brian, was hit by a car and killed, to the shock and dismay of fans. So, they struck back.

Aaron Thompson, of Tuscaloosa, AL, went online to launch a Change.org petition Monday to bring back the martini-swilling pooch, voiced by creator Seth MacFarlane, and within hours had collected 1,500 signatures. There's also a Facebook page (RIP Brian Griffin From Family Guy) which has already gathered close to 100,000 likes.

Thompson wrote, "Brian Griffin was an important part of our viewing experience. He added a witty and sophisticated element to the show. Family Guy and Fox Broadcasting will lose viewers if Brian Griffin is not brought back to the show."

On the episode titled "Life of Brian" the dog was struck by a car while preparing to play in the street with Stewie. His injuries, unfortunately, were too severe, and he sadly died.

The Griffins have already welcomed a new dog to the family named Vinny, voiced by Tony Sirico ("The Sopranos").

When asked why they would kill off such a beloved family member, executive producer Steve Callaghan told E! News, "It seemed more in the realm of reality that a dog would get hit by a car, than if one of the kids died. As much as we love Brian, and as much as everyone loves their pets, we felt it would be more traumatic to lose one of the kids, rather than the family pet."
