Continuity

Notes/trivia

 * It's revealed that Daphne and Velma are roommates in one house, while Fred, Shaggy, and Scooby are also roommates in another.
 * This is the first time in the franchise that a celebrity guest star portraying themselves is the villain.
 * A "Daphanatic" from the direct-to-video film Scooby-Doo! Frankencreepy, (somehow) obtained Daphne's heart-shaped love letter and mugshot.

Cultural references

 * As the gang is getting their mugshots taken, the number "69" is visible, as a reference to the year 1969, which was the year that Scooby-Doo, Where Are You! premiered on television.
 * Each of the extras playing the human Mystery Inc. members are animated caricatures of the actors playing them.
 * Frank Welker as Freddy.
 * Casey Kasem as Shaggy.
 * Grey DeLisle as Daphne.
 * Mindy Cohn as Velma.
 * The episode contains a nod to the live-action movie(s), in which Daphne is appalled at having been played by an extra, exclaiming "Was Sarah Michelle Gellar not available?" in annoyance.

Animation mistakes and/or technical glitches

 * None known.

Inconsistencies/continuity errors and/or goofs/oddities

 * Even though this takes place around Valentine's Day, which is set in February, it instead appears to be set in spring or summer (no snow on the ground, leaves intact on the trees, no visible winter clothes) rather than winter.
