Stan is obsessed with mini-track-race cars and Francine needs to get to the bottom of why he's always staying late after work.
Roger becomes a flight attendant... but soon that apirals out of control...as with everything Roger touches.

*additional*
I edited the description after watching the episode and found out it was the description for episode 09/13 which is released on April 17th.

Klaus gets transferred into the navigation system of Stan's car when Stan refuses to pay for life-saving surgery; Steve and his friends prank Roger, who then terrorizes them for revenge.
