Simpsons: betting on the "outing"

For those who haven't followed, Matt Groenig has promised that a character will come out this season. My bet is on Groundskeeper Willie. Here's the Vegas odds:

Marge's sister Patty was the favorite at 4/5 with Smithers trailing at 4/1 to be "outed." Ned Flanders is posted as 15/1, making the devout-Christian character a long shot; however, several large wagers have been placed on his character, which has come as a surprise to the bookmaker.
