Randi Coy, the 23-year-old first-grade teacher and unwitting mark of the FOX series "My Big Fat Obnoxious Fiance," looked befuddled for much of the show's premiere Monday night (Jan. 19).

Her employers might have a similar look on their faces. The Catholic school in Phoenix where Coy teaches is none too pleased about her taking part in a reality series that uses a fake wedding as bait for a large cash prize.

Bill Langley, principal of Pope John XXIII Catholic School, says Coy, a first-year teacher, took a leave of absence around Thanksgiving to film the show. She has yet to return to the school; a substitute has been teaching her class.

"She has obligations there and she has obligations here," Langley tells the Arizona Republic. "She has to let us know which obligations come first."

The principal has sent a letter to students' parents to let them know of Coy's impending TV stardom. He says he'll wait to see the show before deciding how to proceed, but he's not optimistic.

"You can't be teaching and do a show like that," Langley tells the paper. "There's a certain set of values at a Catholic school. Certainly we have a moral obligation under our faith to make a judgment call, not to pre-judge, but to make a call on that."

Coy went into "Obnoxious Fiance" thinking she would win $500,000 for convincing her family and friends that she's marrying a guy she met on a dating show. The guy in question, though, is really an actor named Steven Bailey whose job is to act as boorish as possible in the days leading up to the ceremony.
