Why was Cinderella kicked off the basketball team?
She ran away from the ball!
Why is it funny? The joke relies on the double meaning of the word “ball.” “Ball” usually means a round thing you play sports with, like a basketball. “Ball” also means an old-fashioned, fancy party, like the one where Cinderella met her prince. At the stroke of midnight, she ran away from the ball, clearly making her a terrible basketball player.
