Take a pinch of "Married by America," add a dash of "The Joe Schmo Show," throw in a jigger of "Trista and Ryan's Wedding" and mix it all in a glass lined with "Average Joe" and you have the entirely original formula for FOX's latest reality entry "My Big Fat Obnoxious Fiance." Advocacy groups for the big, the fat and the obnoxious should stand ready to be offended by the six-episode series, which will launch on Monday, Jan. 19.

FOX can be confident that "My Big Fat Obnoxious Fiance" will find an initial audience. The network is premiering the show at 9 p.m. ET after the premiere of the third installment of "American Idol." It will continue in the time slot which once nurtured "Joe Millionaire," "Married by America" and "Mr. Personality."

"MBFOF" comes from the good people at Rocket Science Laboratories and was nurtured by FOX's own reality mad scientist Mike Darnell.

The premise finds Randi, a 23-year-old first grade teacher from Scottsdale, Ariz., attempting to perpetrate a giant lie on her family. She has to make her family believe that she has gone on a reality show and become engaged to "Steve," the embodiment of the show's title. She thinks that if she can make it through her wedding without admitting that she barely knows Steve, her family will get $500,000.

Randi thinks that Steve is also a reality show contestant trying to fool his own family. What she doesn't know is that Steve is an actor cast to be as obnoxious as possible to destroy the wedding. His friends and family are actors as well.

How could hilarity help but ensue?

Claudia DiFolco, most recently seen on FOX's "Anything for Love," will host.
