Episode title: Everybody's Talking About the Mental Load
After Rebecca tells Dave she carries the emotional labor, aka the "mental load" of the family, he tries to prove otherwise by having her take care of just Deb and Stew for a few days. They both realize they've bit off more than they can chew, especially when Dave enlists his mom to help with Rebecca's mental load.
