Some shows are afraid to tell you too much about their new seasons, but not It’s Always Sunny in Philadelphia, the Best Comedy Series nominee in EW’s third annual EWwy Awards for the Emmy snubbed that returns to FX Sept. 16. The behind-the-scenes clips below confirm that in season 6, the Paddy’s Pub gang will tackle gay marriage, class issues, Dennis’ love life, a fishing vessel (fingers crossed Charlie and Frank watch Deadliest Catch), more pyrotechnics (two words: meat bomb), and Sweet Dee’s pregnancy — which will be revealed in a Halloween flashback episode that has the guys asking whodunit (who knocked Dee up, that is). That episode also produces the return of the fan-favorite McPoyles (Mac gets with the sister?!).

Who do you think will have fathered Dee’s baby? Is this the greatest can’t-believe-how-much-I-actually-care-about-it mystery since Eric Cartman’s father?

P.S. Sunny fans, vote for the show and Best Supporting Actor Charlie Day in the EWwys!
