The fact that this will be broadcast on Fox is somewhat ironic
'Simpsons' Character Coming Out Of Closet
FOX
A long time character on "The Simpsons" is about to come out of the closet. But the show's producers aren't saying who.
The betting seems to favor Waylon Smithers, who for years has harbored a secret crush on his boss, Mr. Burns.
Producer Al Jean said it happens during an episode where Springfield legalizes gay marriage. Reportedly, in the episode, Homer becomes an ordained minister over the Internet and begins performing gay marriages.
The New York Post is speculating that if it's not the obvious choice of Smithers, it may be one of Marge's chain-smoking sisters Patti or Selma.
