The boys learn Terrance and Phillip have gone separate ways and seek to reunite them in time for the "Earth Day Brainwashing Festival"
Terrance and Phillip: Behind the Blow contains examples of:
- An Aesop:Terrance: You know, Phillip and I have learned an important lesson: that when you go through a lot with somebody, you can't let trite things come between you.
Phillip: That's right, Terrance. You should only let trite things come between your ass cheeks. [farts]
- An Arm and a Leg: The Earth Day activists "encourage" the boys to succeed in getting Terrence and Phillip to perform by chopping off Kenny's arm. As things deteriorate, they chop off more and more of Kenny's limbs until he's completely dismembered.
- Ax-Crazy: The Earth Day Brainwashing Committee, HOLY SHIT. As mentioned above, when T&P are running late, one of them chops off one of Kenny's arms, and that was just a warning to the boys!
- Call-Back: Cartman threatens to "make Phillip eat his parents"
- The Movie and Not Without My Anus" are mentioned in the movie
- Career Resurrection: In-universe. Asses of Fire is dubbed a smashing success that revived Terrance and Phillip's careers... as well as helped cause a war that killed millions and nearly got the duo executed.
- Cassandra Truth: The boys really did save their lives, well, Kenny (used a reset to bring them back to life) and Cartman (shut off the electric chairs) did.
- Classically Trained Extra: Part of Phillip's problem is the repetition of doing the same old fart jokes when he'd rather change things up. The boys find him performing in a production of Hamlet.
- Cruel Mercy: One of the few occasions in the early seasons where Kenny doesn't die onscreen. Instead, he's left lying on the ground with his limbs cut off.Cartman: Look, Kenny. Everything turned out okay.
Kenny: Fuck you.
- Feud Episode: For Terrance and Phillip. Their act broke up because Terrance is extremely controlling and takes all the credit, while Phillip chafes under having to do the same thing again and again.
- Formerly Fit: Terrance puts on a lot of weight after parting ways with Phillip.
- Friendship Moment: Watching the Behind the Blow special causes Terrance and Phillip to remember the good times they had together and reconcile.
- No Sympathy: No one particularly cares about Kenny getting his limbs cut off, even ignoring his first anguished scream outright.
- Only Six Faces: Up to Eleven, as all the people in Terrance's performing arts school all look like Ike
- Real Life Writes the Plot: Several parts of Behind the Blow are based off Trey Parker and Matt Stone's experiences in writing South Park.
- Star-Derailing Role: In-universe. The backlash against Not Without My Anus purportedly damaged the duo's careers, sending them into a spiral of drug abuse and suicide attempts.
- Take That, Audience!: The backlash towards "Not Without My Anus" is portrayed as an attack on the studio where people got killed.
- To the Pain: Kenny's fate in this episode, ironically he doesn't die. (Onscreen, at least. He most likely died of blood loss afterward, as he has all his limbs next time he appears.)
- Would Harm A Child:
- The Earth Day activist certainly seem to have no qualms about dismembering a nine-year-old boy.
- In a state of depression over the reaction to "Not Without My Anus", Phillip beat up a child.
- You Didn't Ask: Kyle uses a very vague variation of this to get Phillip to come to South Park.
