The truth about lying and laughing

Covers psychology of lying and telling jokes. A lot of the text is quotes. The author's favorite joke cited at the end:

A dog goes into a telegraph office, takes a blank form and writes: 'Woof, Woof, Woof, Woof, Woof, Woof, Woof, Woof, Woof.'

The clerk examines the paper and politely tells the dog: 'There are only nine words here. You could send another "Woof" for the same price.'

The dog looks confused and replies, 'But that would make no sense at all.'
