Both Part One and Two of this episode are available on home video.
After Launchpad pulls the tire off Darkwing's head, the camera pulls out and you can vaguely see a picture of a bikini-clad pin-up girl picture in the background of Launchpad's hangar.
Gosalyn: Keen gear! You guys must be arch-enemies, just like in the comics!
Darkwing: Actually, he doesn't even know my name.
Gosalyn: I don't know anything about a pig and I was nowhere near the boy's bathroom at the time!
Mrs. Cavanaugh: What pig?
Gosalyn: Oh, I ment big! As in big of you to take such an interest in me! How may I help you?
Darkwing: I never want to see you again, EVER!
Launchpad: Okay. So, do you want my phone number?
Hammerhead: That's it, boss. I'm a stooge! Just call me Curly!
Not only is this an obvious referance to the Three Stooges, but Shemp Howard [One of the stooges] played a character named Hammerhead in the Universal horror-comedy The Invisible Woman in 1940.
