Spongebob Squarepants - Maximum Capacity!
In the episode of Spongebob Squarepants titled "Sailor Mouth," in the beginning, Spongebob and Patrick use swear words, causing the Krusy Krab to empty. As the customers leave, the screen zooms to a sign on the outside of the Krusty Krab that says, "Maximum Capacity." As the customers leave, the number on the small sign rapidly shoots down, but a maximum capacity number wouldn't go up or down...it's the capacity, not the number of people inside!
