Ralph and Alice are contestants on Beat the Clock. They succeed on their first stunt, where Alice has to propel a cup with a can of whipped cream into a net Ralph is holding in his teeth, and are in the middle of their second, where they have to catch lemons in a cup and stack the cups while keeping a balloon from hitting the ground, when time runs out and they're asked to return the next week.
