Q: Why do soccer players do so well in math?
A: They know how to use their heads!
Explanation: To ”use your head” means to think. People who do well in math use their heads when they think and solve math problems.
Soccer players also use their heads when they “head” the ball. Yes, in English, the word “head” can also be used as a verb.
This joke is funny because it plays on the double meaning of “use your head.”
Happy birthday, friend!!
