Fox is building a bridge between Brooklyn Nine-Nine and New Girl.

The network announced Monday at the Television Critics Association summer press tour that the veteran comedies — and newly-minted Tuesday timeslot companions — will partake in a crossover event this fall. The one-hour stunt will air Tuesday, Oct. 11, beginning with Brooklyn Nine-Nine at 8/7c and concluding on New Girl at 8:30/7:30c.

Regarding the plot, Fox would only share that the New Girl crew will travel to Nine-Nine‘s Big Apple turf (we’re guessing fledgling cop Winston plays a central role).

Fox is no stranger to mashing up its franchises. Last season, the network cross-polinated Bones and Sleepy Hollow, a gambit that earned both series’ its best ratings of the season.

In a tongue-in-cheek statement, Brooklyn Nine-Nine co-creator Dan Goor revealed that this was the first of many synergy-fueled gimmicks to come. “Stay tuned for our two casts to do a soulful R&B number on Empire, co-anchor the FOX 10 O’Clock News and connect for a touchdown on NFL Sunday.

“But in all seriousness,” he added, “we’re all huge fans of New Girl here at the Nine-Nine, and we’re excited to see our characters interact and to work with their incredible writers and producers. And also to see what their craft services are like, compared to ours.”

Not to be outdone, New Girl creator Elizabeth Meriwether released a satirical statement of her own. “The crossover episode has historically been the artistic high point of any show that has dared to attempt it,” she said. “Maybe you remember ‘Blackout Thursday’ on NBC, or even further back the infamous Alf/Gilligan’s Island crossover of the late 1980s. [We] will proudly and humbly go where few shows have gone since the 1990s. We know we have big shoes to fill, and we look forward to disappointing everyone. There’s a 50% chance Alf will also be in both episodes. But there’s also a 50% chance that is a lie.”

Brooklyn Nine-Nne Season 4 and New Girl Season 6 will premiere on Tuesday, Sept. 20 on Fox.
