The Andersons go on vacation to Lake Winnibigoshish, WI.

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 Louie's head swells up to gigantic red proportions, he knows there is something wrong, but does not want to face the awful possibility that he has allergies and must, therefore, get an allergy shot!

Dad loves his car like it's another member of the family, so when it stops running, Dad feels as though a family member is very, very sick.
