Here's A Hilarious Preview Of 'The Simpsons' And 'Family Guy' Crossover That's Coming

The two royal families of cartoon TV are combining forces.

Our beloved and enigmatically-located Springfield takes in some "albino visitors" according to Homer Simpson, when "The Simpsons" and "The Family Guy" combine for "The Family Guy" season premiere on Fox.

Entertainment Weekly is hosting the episode's (aptly titled "The Simpsons Guy") nearly five-minute preview, which was debuted at San Diego Comic-Con on Saturday.

Bart and Baby Stewie prank call Moe (spoiler: Stewie kinda misses his mark).

And the two families seem to be getting along well, especially Homer and Peter, who head to Moe's Tavern for a beer.

And, well, things only get weirder from there in the preview, but we'll let you see for yourself. The hour-long "The Simpsons Guy" airs on September 28 on Fox.
