Mug puddle - The water, captured on the bottoms of inverted cups located on the top shelf of the dishwasher, forms a small puddle and can be used to indicate the dishwashing cycle is complete.
For example, Pearl asked, "Hey, are the dishes clean in the dishwasher?" Earl answered, "I don't know. Are there any mug puddles on the coffee cups? If so, the dishes are clean."
