Family Guy season 18 is looking like it's going to ramp up the weirdness factor by a lot. Fox released the trailer today at San Diego Comic-Con. Series creator Seth MacFarlane and the rest of the cast were on hand at the annual event, promising that the long-talked about movie is still going to happen. MacFarlane says the big screen adaptation is on his "to do list" and that he already has a premise set up. While that project isn't going to be out for a while, Family Guy season 18 kicks off this fall and unites Peter with Beavis and Butthead.

Released at San Diego Comic-Con earlier today, the four-minute trailer for Family Guy season 18 is a little all over the place, but that is exactly what fans have come to expect from the show over the years. Peter sits on the couch with Beavis and Butt-Head while wearing a Boyz II Men t-shirt with some ridiculous 90s hip hop hair. Elsewhere, Quagmire takes on living with over 70 cats and Peter can't decide which beverage he wants with cat hair in it.

Meg finally gets a boy to tell her that he loves her, only for him to die right after. This leads to what looks like a Weekend at Bernie's situation, but with a boyfriend for Meg. In a typical Family Guy fashion, it's weird, dark, and it goes on for way too long. Seth MacFarlane and crew have been delivering the goods for years now, so it will be interesting to see how that equates on the big screen after so many years of doing the show.

As for Family Guy lasting for 18 seasons, Seth MacFarlane never thought it would reach this point. The show has survived cancelation and is one of the most beloved animated shows in history, right up there with The Simpsons, which is now preparing for its 31st season. MacFarlane had this to say about the show's longevity.

"I never thought it would go this long, in my wildest dreams .. I think animation sort of exists in its own bubble universe that is so far moved from reality... It's a strange beast that's living outside the rules of proper society as we know it."

Family Guy season 18 will premiere September 29th and things are going to get pretty strange. After going on for so long, many have often wondered if there will be any other spin-offs, particularly with Brian and Stewie. Seth MacFarlane didn't rule the idea out, but it doesn't sound like something he is interested in. He says, "I think Family Guy would have to expire (before that happens)," which is understandable. "I think, at this point, Family Guy is going to outlive me," concluded MacFarlane. At this point, he's probably right. The series shows no signs of slowing down now.
