The episode title here says it all. It's Always Sunny in Philadelphia is preparing to shoot an episode titled, "Dennis Gets Divorced." Presumably the episode will be preceded by one titled "Dennis Gets Married", since as of now the guy's single.

In the FX comedy's sixth episode of the new season, Dennis (Glenn Howerton) will have finally had it with his new wife, Maureen, and her 'crafty' ways. (She's in to arts and crafts.)

Turns out Maureen has a brother, Bill, who will also be getting dumped -- by Dee (Kaitlin Olson), who understandably is put off by Bill's shrewish wife Jane and his trampy mistress.

The seemingly only happy couple in this show? Charlie (Charlie Day) and Frank (Danny DeVito), who will pose as domestic partners to get a discounted rate at a strip club.
