17 year old Cary Steckler masterminds a plot to humiliate his high school tormentors (Shawn H. Smith as 'Andre', Drew Tyler Bell as 'Chuck', and Scout Taylor-Compton as 'Tina') by kidnapping them and 'putting them on trial' live on the web, and Emily and Matt have to revert to younger versions of themselves (she the picked-on, he the bully) to get through the teens and prevent tragedy...
The title comes from the Patti Page song "Throw Mama From the Train, a kiss, a kiss, Wave Mama from the train a goodbye..." Cameo: [Rob Reiner] Larry's character's agent.
