Step by Step - Season 3 - Eps 11: Christmas Story
After Carol presents an idea of exchanging fewer gifts, Frank announces he gets a 20% discount at Hartman's Toy Store because of his remodeling work there. Both believe one has picked up Brendan's train set and therefore, neither does. When they realize this on Christmas eve, they use Frank's key to get into the toy store and are leaving money in the register when Deputy Barney Feif notices them. They are taken to jail where they are detained. After the kids open all their presents without knowing where their parents were, Cody points out that Christmas should be about joy and loved ones. The kids realize their mistake, get concerned, and find out their parents are in jail. They bring food and caroling to the jail. Deputy Feif lets them out and they all go back home to celebrate Christmas, even Barney.
