Doug and Carrie realize that they need to give more to charity, so they donate to Kirby's school library fund. They donate enough money to be listed on the Patrons of the Library plaque, but due to an error of leaving a zero off their amount donated, they are only listed as "friends" instead of "patrons". Doug doesn't want to make a big deal about it, but Carrie insists that they get the credit they deserve. After trying to correct the mistake, another is made - listing the donation at $5000 instead of $500. This time, Carrie wants to keep the recognition without having to pay the price.
