Q: Why did Cinderella get kicked off the football/soccer team? 
A:Because she ran away from the ball!

Explanation:  Cinderella went to that fancy dance party in her fancy dress.  That fancy dance party is called “a ball.”  So is the sphere that soccer/football players kick- a ball.  This joke plays on the word “ball” which can mean a fancy party with dancing, or a ball for playing sports.

This joke is funny because soccer players can’t run away from the ball!
