Q: What did the math book say to the psychologist? A: “Would you like to hear my problems?”\nWhat do you think is the punchline of the above joke?
Explanation: A math book has problems, many math problems. The purpose of a math book is to teach you how to think like a mathematician and to solve math problems.
A psychologist can help you with problems with feelings or behaviors; a psychologist cannot help you with math problems.
This joke is funny because it plays with two different ideas of problems: math problems and psychological problems. And of course, math books can’t talk!
