Try "are you smarter than a 1st/2nd/3rd/4th/5th grader?" Have kids answer questions that they would know according to their grade level and staff answer matching but ridiculous questions.
5th grader is asked "What is the area of a square that is 2 inches by 2 inches?" "4? Correct!"
Staff is asked "What is the color of a square that is 2 inches by 2 inches?" "Blue? WRONG. The correct answer was that it is an invisible square and therefore has no color."
