Behind the scenes

 * With every episode's title card, one of the gang announces the guest star, which is Fred this time.
 * This is the second celebrity guest after Mark Hamill to come from a Star Wars movie. His role as Lando Calrissian is naturally referenced and the Sky Town Cool School is a reference to Cloud City from 1980's Star Wars Episode V: The Empire Strikes Back.
 * Daphne says "Jeepers" once.
 * Shaggy says "Zoinks" once.
 * Fred says "Hold the phone" once.
 * Jeeves is simply credited as "Accountant."
 * Tom and his brother are simply credited as "Nerdy brothers."

Errors

 * Velma refers to Interlaken as a city, while the map that's shown as she says this refers to Interlaken as a town, which is correct if it's the real town in Switzerland.
