Mr. Herriman's uptight agenda for strict scheduling starts to become a nuisance to the Foster's residence, so they band a plan to make Bloo get Mr. Herriman to loosen up, which he successfully does and becomes a new man... er, rabbit with a hippie lifestyle and redubs himself as "Harry"! But it ends up backfiring as Harry ends up being a wee bit too loose.
This episode provides examples of:
- Actually Pretty Funny: What causes Herriman to break is him laughing at Bloo getting attacked by a flock of angry chickens.
- Black Comedy: Coco's plan to deal with Herriman is mentioned to be illegal by Eduardo and Frankie. While it's unclear what Coco's plan was, her picking up a baseball bat implies what she was planning.
- Brick Joke: After Bloo turns Mr. Herriman into Herry, he decides to streak, which doesn't surprise Frankie, since he doesn't wear clothes to begin with. Near the end of the episode, when Herriman is back to his normal self, he orders Bloo to put some clothes on. In The Stinger, Bloo is seen grumbling as he now has to wear a white shirt, black necktie, and brown pants that are way too big for him.
- Disproportionate Retribution: Herriman nearly allowed Bloo to get adopted all because Mac was ten minutes late.
- Fatal Flaw: Harry!Herriman's big flaw is his lack of responsibility. As due to him being way too loose, he's unable to help the house like Herriman did. And it even makes him not take the direness of situations (bills being overdue) seriously.
- Gone Horribly Right: Bloo does successfully get Herriman to loosen up, but it ends up causing the house to get messier, families
- Jerkass Has a Point: Bloo is right to call out Herriman that he takes everything too seriously when he even takes an expression he said - Bloo saying he'll make Herriman will have fun even if it kills him - seriously.
- Negated Moment of Awesome: Just as Bloo manages to properly have the ball hit the paddle, Herriman confiscated the paddle-ball due to being so uptight.
- Only Sane Man: Mac, Frankie, Wilt, Eduardo and Coco are the only ones who are aware of the deteriorating conditions at Foster's.
- Please Put Some Clothes On: When Herriman is back to his normal self at the end of the episode, he starts barking orders. One of his orders is for Bloo to put some clothes on, which Bloo is forced to do in The Stinger.
- Round Hippie Shades: Subverted. While he's "Harry", Herriman wears star sunglasses instead.
- Streaking: Played with; after Bloo turns Herriman into Herry, leaving the residents of Foster's to do whatever they want, things begin to spiral out of control. At one point, Bloo runs past her, telling him he's streaking. Frankie points out that it doesn't surprise her, since he doesn't wear clothes to begin with, to which he tells her "And I never will!"
- Talking in Your Sleep: Frankie does this not once but twice when she has, err, fantasy dreams about action star Rod Tango.
- We Want Our Jerk Back!: Frankie outright admits Harry causes more problems than uptight Herriman.
