In the twelfth episode of The Big Bang Theory‘s season 7 (S07E12) Sheldon tries to learn how to be funny. On his mission he even studies a book on that topic.

Sheldon chose Jon Macks’ book from 2003 How to Be Funny: The One and Only Practical Guide for Every Occasion, Situation, and Disaster (no kidding).

The book has mixed reviews on Amazon from “It’s funny and helpful!” to “More sad than funny”.

I guess it’s obvious that the book didn’t help Sheldon in his quest to be funny. :)
