This vignette sacrifices suspense (and credibility) in favor of cuteness, with of course the title giving away any possible surprise.
Story unfolds in perfunctory fashion: Kylie Rocket shows up as an unlikely cleaning lady (supposedly a student who needs the money) at Coco Lovelock's house. Coco, so familiar to fans as the leading underage-look petite starlet in porn, has high heels and an affected accent as the lady of the house, literally clutching her string of pearls. She criticizes Kylie's work (hence the titled "Missed a Spot") and the camera is strictly focused on Kylie's rump, her panties showing as she's down on the floor scrubbing away.
This very weak segment is just a couple of gal pals roleplaying, as is made explicit in the lame ending to the scene. It's so obvious that Coco is miscast as a posh married lady that we know it's just a dumb game right from the beginning of the show.
