Assembly Line Panic
The stuff on the belt is just a bit too fast for our hard-working friends.
So, the characters have decided to make an honest living. Their task is something simple: take the stuff off of the conveyor belt, maybe wrap it up. They've been warned, however, that if they miss so much as one thing, they're fired! So, they start the belt. It starts slow at first, but it starts going faster and faster. Hilarity ensues as they frantically try to keep the stuff away from the end. Popularized by I Love Lucy, with chocolates, but has been imitated all over the place, especially in kid's shows.
Hello, Unknown Troper. You'll need to get known to lend a hand here.
