Mother's Day for Frankie is anything but serene when she finds herself doing more for Mike and the kids and less for herself. But she learns that the apple doesn't fall far from the tree when she escapes the family for a few hours to go to her mom's (Marsha Mason, "The Goodbye Girl," "Chapter Two") and ends up acting like a child by making her mom wait on her hand-and-foot. Meanwhile, Sue feels guilty when she steals a motivational magnet from a store whose message actually enticed her to shoplift it.

While Frankie's parents Tag and Pat visit for Christmas, Mike is less than thrilled. To make matters worse, the Hecks have a disagreement with them over Frankie's idea on how to celebrate the holiday without exchanging presents

Frankie has a meltdown and forces the family to make significant changes to their lifestyle. But just as she puts these changes into effect, she leaves them to spend a some time relaxing with her mother.

Frankie's parents, Pat and Tag, invite the Hecks to spend a few days at their house to celebrate Thanksgiving together. But the festivities begin to fall apart quickly when Frankie's sister, Janet, and her family also join in, and soon the siblings are at each other's throats over their widely differing parenting techniques. Meanwhile, Mike tries to offer some advice to Axl on how to pick up girls when he witnesses his son trying to impress a pretty mini-mart cashier - and fails miserably; Brick attempts to prove his innocence when he is accused by Janet of damaging her daughter's expensive toy; and Sue is stoked when Frankie, Pat and Janet invite her to take part in their gossip sessions.

Frankie tells the family that they don't need to do anything special for her this Mother's Day, but she decides to have everyone pull a family member's name from a hat and do a nice deed for that person after a kind stranger asks her to pay it forward.
