Mac and the imaginary friends join Madame Foster's bowling team to help her beat her rival, Jerkins. Mac ends up getting kicked off the team and learning from a bowling expert, while the rival team promises Bloo a paddle ball if he joins them and helps them win.
This episode provides examples of:
- Anti-Mentor: Mac gets lessons from an imaginary friend named Bowling Paul, who supposedly won all the trophies on display in the bowling alley. But when he tries to put his lessons (which are mostly of the "one with the ball" variety) to practice, he ends up wrecking the place. Turns out Paul was the imaginary friend of the owner, who won all the trophies, and Paul himself has no bowling skills whatsoever.
- Bowling for Ratings: The Fosters gang goes to a bowling alley to take part in a tournament with Madame Foster's team.
- Handicapped Badass: One of Jerkins' teammates is confined to using a motor scooter to get around. Nonetheless, she proves that this is no problem for her as she uses the basket to score a strike.
- Here We Go Again!: After Bloo gets his paddleball and can't hit the ball, an imaginary friend named Paddle Paul offers to teach him how.
- Hidden Depths: Bloo showcases to be a skilled bowler... without even trying!
- Jerkass Ball: Madam Foster holds this throughout the episode, acting like a Raging Shrew and yells at Mac constantly, simply because she's mad that they aren't going to win. Then the plot twist being they weren't competing to win, but just to outdo her rival.
- O.O.C. Is Serious Business: The normally nice and sweet Madame Foster becomes very fierce with a zero tolerance for failure disposition in a game of bowling to the point that she begins calling 8-year-old Mac worthless for his lack of bowling skills. Yeah, she really gets into the game.
- Serious Business: The bowling game.
- Shout-Out: The name of the episode is a reference to The Big Lebowski. Caricatures of The Dude, Walter and Donny appear in one scene.
- Villain Has a Point: Jerkins essentially steals Bloo away from Madame Foster's team with a paddleball, and Foster expresses disgust that not only would she steal away her teammate when Jerkins already has enough, but she would sabotage one of her own just to make room for Bloo. But Jerkins is not impressed, as she argues that Madame Foster is not paragon of Undying Loyalty either: she did trade-off Mac for Bloo when it was convenient. At realizing she has no high ground, Madame Foster is stunned speechless.
