'Desperate Housewives'' Teri Hatcher in a Fat Suit!

In the aftermath of the plane crash which puts Karl (Richard Burgi) in the hospital, Susan (Teri Hatcher) contemplates what her life would have been like if she had not left him -- and in her fantasy, she packs on the pounds when she realizes he hasn't quit his cheating ways!

So, she thinks about getting a little revenge. She tells Mike Delfino (James Denton), who is not her husband in the fantasy, "You know what would serve him right? To come home and find me in bed with another man!"

Also in the episode, airing Sunday, January 3, at 9 p.m. on ABC, Bree (Marcia Cross) imagines what her life would be like if she divorces Orson (Kyle MacLachlan) and marries Karl; Carlos (Ricardo Antonio Chavira) fantasies that Gaby (Eva Longoria Parker) is an over-protective mom; and Angie (Drea de Matteo) wonders what her life will be like if Mona (Maria Cominis), her blackmailer, survives.
