Crossing the Line Twice: Crossed with Jerkass. If during Speedmouse we believe that the Roadie had the Remote the whole time then the truck running over the imaginary girl was his fault.
Shocking Swerve: Played for laughs at the end of Speedmouse - All through the show Tina (the deep voiced stage manager) has been expressing outright love to a confused and worried Dave and acting like a douche to ShawnShane; and the roadie has been very nice to Shane while treating Dave like crap. At the end, Dave pulls the clown mask off Roadie, revealing another, identical mask underneath. Both Umbilical Brothers cry out in surprise, "TINA?!", and then the show finishes. Also a bizarre instance of The Reveal and The Un-Reveal occurring at exactly the same time.
Too Good to Last: The Upside Down Show only lasted for 13 episodes, and it was AWESOME!
