'The Last Man on Earth' exclusive clip: Phil and Carol talk about Carol having sex with Phil

And then there was one.

Yes: Only one episode is left of the show about a man who thought he was the only one left. He was wrong about that. He was wrong about a lot of stuff, actually. And in the season finale of The Last Man on Earth, the chickens—and possibly cows?—will come home to roost for Phil “Tandy” Miller (Will Forte), who is headed for a showdown with Phil “New Phil” Miller (Boris Kodjoe). He’s also seeing Carol with new eyes as she spends some quality time with the new Phil, if you know what we’re saying.

If you don’t, what we’re saying is “casual sex.” It’s a concept that Carol is about to explain to old Phil in the following clip from “Screw the Moon,” which airs Sunday at 9:30 p.m. on Fox.
