Jacobo: So long, suckers. (glider begins to brake) Agh! Help me, suckers!

Jacobo: I would have gotten away with it... if it weren't for those meddling punks, and their dumb dog!


  • The original Pterodactyl Ghost in The Scooby-Doo Show was Johnny, who operated a delivery truck, and his criminal activity was about bootleg cassette tapes, not bank robbery. This is such a significant continuity difference that Jonathan Jacobo should probably be regarded as a different character than Johnny, either an AU version or a second criminal who used a Pterodactyl disguise.
