Fox is airing a brand new episode of American Dad tonight, called "Introducing the Naughty Stewardess." In "Introducing the Naughty Stewardess," Roger forges a radical plan to help Steve date the hot girl at school (guest Voice Ellie Kemper). Roger will switch faces with Steve "Face/Off"-style, seduce her, then tag Steve back in after she's fallen for him. But, Roger soon decides he may actually want to keep her for himself. Meanwhile, Stan and Francine become "Charlie's Angels"-type airline stewardesses to thwart an evil plan by Mark Cuban (guest-voicing as himself) to blow up the sun. The voice cast includes Seth MacFarlane as Stan Smith and Roger the Alien; Wendy Schaal as Francine Smith; Rachael MacFarlane as Hayley; Scott Grimes as Steve; Dee Bradley Baker as Klaus; and Jeff Fischer as Jeff. Guest stars are Beckie Newton as Margie, Gillian Jacobs as Christy, Olivia Wilde as Denise, Megalyn Echikunwoke as Angie, Ellie Kemper as Jenna, Kyle Chandler as Coach Brian Sanders and Mark Cuban as himself. American Dad, "Introducing the Naughty Stewardess," airs Sunday, March 16 at 7:30 PM ET on Fox.
