Cyberchase: The King's Jester
Math → Averages → Median
The jesters are auditioning for the king and don't know if the king is short or tall. They want to send someone who is not too tall and not too short so as not to insult him, but they don't know which one of them fits that criteria. The CyberSquad lines the jesters up from shortest to tallest and repeatedly takes one away from each end of the line to find the jester that is the middle height.
