Doug's Bluff Scout Troop #617 has to raise money for new canoes, so they sell "Bluff Scout Booster Bars" door to door. But after being rejected by everyone, Roger offers a new way to sell the bars, which Doug doesn't agree with. Then when Doug sells a bar to Mr. Swirly, he realizes the problem of why the bars taste so horrible. Over the weekend, Doug puts on a few pounds at Grandma Funnie's house and has been invited to Beebe's pool party. Doug is so embarrassed to be seen in a swimsuit, so he decides to work the extra weight off before the party using Ronald "Prepare to Suffer" Weisenheimer's videos.
