Video Summary

On the island of knights and knaves, knights always tell the truth while knaves always lie. When questioned, the taller man's response was unclear, suggesting he spoke a paradox, indicating he is a knave. Since the taller man cannot be a knight, both cannot be knights. The shorter man was asked if the taller man was a knight. With the taller man's status known as false, the shorter man's truthful response, confirming this information, means he is a knight. Therefore, the taller man is a knave, and the shorter man is a knight.
