Stanley telling off his boss after once again arriving late for work.
Stanley: BACK off, monkey boy, or I'll tell your daddy that you're running the place like it's your own personal piggy bank. Or maybe we should call the IRS and see if they could arrange a vacation for you at Club FED!! Mr. Dickie:[visibly shaken] That will be all Ipkiss. [walks away]
Stanley fighting Dorian without the power of the Mask.
Dorian: I'm gonna take you apart!
Stanley: Well, I hope you can enjoy the victory with ONE FRIGGIN' EYE! (pokes Dorian in the eye)
Stanley punching him so much. Later, he gives Dorian a Megaton Punch for grabbing his hair.
The Mask's entire dance sequence with Tina at the nightclub, where he sports his signature yellow zoot suit.
Tina demonstrates that she's more than your typical Dumb BlondeFemme Fatale by tricking Dorian into taking off the mask and kicking it out of his grasp.
"You were good, kid, real good. But as long as I'm around, you'll always be second best, see?"
From the cartoon: The Mask taking down Cookie BaBoom (the mayor's psycho stripper ex who crashed his bill-signing ceremony) by dressing as a bartender and yanking the dynamite belts that were covering Cookie's body, then using her nudity to distract Kellaway and Doyle in "Flight as a Feather." It's not only awesome because The Mask actually did something heroic (even though he only did it to get his fedora feather back), but it stands out as a testament to how wild kids' cartoon content can get (back then, this episode ran with a TV-Y7 rating with that part intact).
