Being a dad is a full-time job, but what did Danny Tanner, Jesse Katsopolis, and Joey Gladstone do after their girls went to bed on Full House? Fight crime, of course.
The boys explained how they're actually working on another reboot, besides Fuller House, called Full House Nights. "We play adult roommate detectives who've seen a little bit too much," Coulier said.
"The basic premise," Stamos added, "is that after the Tanner kids go to sleep, the Full House daddies, we go out and we go on the mean streets of San Francisco and we solve crimes."
Saget then thanked Stephen for playing a role on their show, prompting The Late Show host to show a clip from the new "series," complete with the opening credit sequence.
In addition to shading Mary-Kate and Ashley Olsen even more for refusing to take part in Fuller House, the clip consists of the three dudes playing "good cop, bad cop, impressionist cop," as they interrogate Dimitri (Colbert) about the next shipment of drugs. FYI, someone's getting ganked.
