Here's a fun one, one of my particularly old ones. I'm sure by now you've seen these characters before on the blog. They're from The Grim Adventures of Billy and Mandy. The boy's Billy and he's an idiot. The girl's Mandy and she's cynical and evil. Together, they hold the leash to the Grim Reaper. It's kind of a gross-out show.
Case in point, this episode here, "Dumb Luck". The premise is that Billy spilled salt, and since he didn't throw it over his shoulder, he's got absolutely terrible luck. One of the things to cap of his humiliation is when someone pulls a thread on his outfit, and his clothes completely unstitch, leaving him naked in school before the next scene begins and he's fine.
For this one, I actually redid the story in a fanfic, "No Such Luck", found on my Inkbunny. The idea was to switch the situation to star Mandy instead, as a way of giving her what's coming to her. There's ultimately only one nude scene in the whole thing, and it pretty much amounts to this one here. The premise is, for a quick gag, Mandy gets unstitched like Billy did, and upon realizing it, flatly covers and says she doesn't care anymore before scuttling off. Just that single picture does the job.
