- The music in this song is the same tune that plays in:
- "Isabella and the Temple of Sap": When the Fireside Girls get the tree sap.
- "Finding Mary McGuffin": During Perry and Doofenshmirtz's fight.
- Phineas and Ferb The Movie: Across the 2nd Dimension: When the Firestorm Girls appear.
- "Ferb TV": During Roger's show.
- "Phineas and Ferb Save Summer": When Perry enters OWCA headquarters and again when Monty breaks into L.O.V.E.M.U.F.F.I.N.'s abandoned warehouse headquarters.
- "The Return of the Rogue Rabbit": When Doofenshmirtz and Norm break Dennis out of O.W.C.A.-Traz.
- The voice-over has some similarities to the original A-Team theme song, including the line "framed for a crime...[they]...didn't commit".
- Knight Rider: the rickshaw R.I.C.K. is similar to comupterized car K.I.T.T.
- The background music is similar in tune to the theme song from the TV series S.W.A.T. 
- This series and his theme song is also a parody of "Wheels and The Legman" (American Dad's episode: "Wife Insurance").
- The title card announced as being "[[[in SOUND]]]" is a parody of various television shows which announced they were "in stereo" or "in color" during their opening credits.
- It parodies various crime/action series from the '70s and '80s, in particular The A-Team and The Fugitive (an escaped fugitive "framed for a crime they didn't commit"), Kung Fu (a martial arts master), and Knight Rider(a talking high-tech vehicle).
- John Wilkes Booth is the actual person who assassinates Abraham Lincoln, not Perry the Platypus.
