It's really worthwhile to read a book of his sayings.
He's a very endearing figure.
The Pleasantries of the Incredible Mulla Nasrudin (Compass) https://www.amazon.com/dp/014019357X/
I don't think it's a book to purchase if you're going to study Zen.
I also get the feeling that some scholars and religious authors tend to make him a cartoonish figure in order to deal with his different perspective.
