Q: Why are pigs so bad at soccer?
A: They are always hogging the ball!

Explanation:  To “hog the ball” means to keep the ball to yourself and not pass the ball.  A good soccer player looks to his or her teammates to see who has the best chance to advance the ball toward the goal; a good soccer player does not hog the ball.

This joke is funny because another word for a pig is a hog
