What are some examples of the usage of humour in non-fiction?

Question

Please cite examples, preferably easily accessible works, of instances where humour (as a device) is used in non-fiction works or works purporting to be non-fiction. I've already come up with some of my own (to be used to substantiate a school project), but the more the merrier, so that I can have a wider range of works to look at.

Answer 1

Answer 2

Making the claim that our president has a triple digit IQ and is not a psychopath?  :))
