Q: Where did the baseball keep its lemonade?
A: In the pitcher!

Explanation:  It is the end of summer, the end days of baseball and lemonade.  School starts tomorrow (and as a teacher I love that!).

The word pitcher has two meanings: a pitcher is a container used to serve drinks; a pitcher is the person on the baseball team who throws the ball toward the bater at home plate (isn’t Mo’ne Davis amazing!).  This joke is funny because it plays on the double meaning of the word pitcher.

Thank you, Daniel, for the joke!!
