Cruella: A mood ring! I really need this! My last one exploded.
Spot: What's Roger up to? He's acting weird.
Cadpig: Maybe he's got a wedgie!
Cadpig: Are you all aware that tomorrow is Valentine's Day? A joyous celebration of the power and importance of love and friendship, and the ultimate guilt trip: The opportunity to give a Valentine to someone who didn't give you one, and watch 'em squirm. I love it!
Spot: She scares me sometimes.
Rolly: Only sometimes?
Aside from "A Christmas Cruella", this was the only holiday special of the series, yet it didn't air anywhere near Valentine's Day.
Roger: I'm working on a new video game... the Lunchbox of Notre Dame!
This is a reference to the film The Hunchback of Notre Dame.
The song that Roger recorded on his valentine for Anita is a parody of the nursery rhyme, This Old Man.
