When Quackerjack releases his giant mechanical teeth they are of equal size, but the ones that chase Pat and Pat and Darkwing somehow become very large while the one that Gosalyn scares off with a dental drill somehow become very small.
Sometimes the head band on Gosalyn's 5-D glasses goes around her head all the way and sometimes it doesn't.
When Darkwing, Gosalyn and the others drive through Whiffle Town in a tour bus, they are being driven by a bus driver and Gosalyn and the female Pat are on on one side behind the driver sitting in a single seat and Darkwing is on the other side. After they come across the giant sized Crying Crissy Doll, the male Pat is the driver and everyone is in the front bench seat.
When seeing Quackerjack getting eaten by the crocodile, Gosalyn shields Darkwing's eyes and she says, "Don't look, dad." She said it right in front of the Pat and Pat (male and female). This is one example of how through out the series, Gosalyn often called Darkwing "Dad" in front of other people, which could put Darkwing's secret identity at risk.
Quackerjack: I like coffee, I like tea, I like toys and they like me! I see London, I see France, I see Whiffle Boy kicked in the pants!
Drake: Any super-secret crimefighter worth his salt is never far away from a closet!
Darkwing: I am the bubblegum that...clings to your shoe!
Quackerjack: Ladies and gentlemen, I am pleased to announce...PLAYTIME!
Darkwing: I am the terror that flaps in the night! I am the wrong number that wakes you at 3am!
This is the first appearance of Quackerjack (despite the fact he appears in the earlier aired episodes "Days of Blunder" and "Just Us, Justice Ducks")
Whiffle While You Work: The episode title is a play on the song Whistle While You Work from the Disney movie "Snow White and the Seven Dwarfs".
