Louie Anderson tells the story of a typical Christmas season when growing up in Cedar Knolls, Wisconsin during his childhood. Young Louie and his family go through the usual routine every family goes through during the season--with some hilarious results! Everything from buying a Christmas tree for the steep (at that time) price of $35, to putting up Christmas decorations for a lonely neighbor (who turns out to be Jewish), to actually opening presents on Christmas Day.

The Andersons get new neighbors, the Johnsons, and Andy immediately starts fighting with Mr. Johnson. Meanwhile, the town of Cedar Knolls gets flooded due to severe rainstorms and the only house that isn't flooded is the Anderson's--thanks to a ten-foot wall that Andy constructed to keep the Johnson's dog out of his yard. Eventually the entire neightborhood seeks refuge in the Anderson home, much to Andy's dismay.

Louie makes a deal with his Dad to get out of his much-hated gym class if he agrees to play little league baseball. Much to Louie's dismay and bad luck, his baseball coach ends up being his tyranical gym teacher. After the coach is hit in the head by Louie's bat during a game Louie's dad Andy steps in as the coach and whips the team into shape in true military fashion--literally. While Andy is teaching the team battle strategies, Louie's mom teaches them actually baseball tips and tricks on the side. Of course in the end, Louie's team ends up in the big championship game and the team's newfound skills are put to the test.

When Ora and Andy leave to go and visit Ora's sick mother, Louie and Tommy are left home alone to fend for themselves during a blizzard.
