Trivia / Phineas and Ferb "Rollercoaster"

• Blooper: When Linda drives Candace in the car, her pink headband suddenly turns yellow. This goof is also left in in the musical version.
• Voices in One Room: Ashley Tisdale and Caroline Rhea recorded their lines together for this episode, since it includes a lengthy dialogue between their characters.
• What Could Have Been:
  • There was originally a joke where Doofenshmirtz told Perry he was too late to stop him, but then checked his watch to see if it was eleven o'clock. This gag would later be used in "Gaming the System".
  • Doofenshmirtz's name was originally "Mittleshmirtz", but it was changed when it was discovered that "mittelschmerz" was a term associated with women's menstrual cycles.
  • Phineas's announcement originally had him say, "Some day you'll be telling your grandchildren about your ride on the coolest! coaster! ever!" This line would later be used in The Musical.
