I remember another section from Catch 22 that made me laugh.
The writer gives a detailed background to each of the soldiers in the book, and one soldier in the book had a father who was a farmer.
His father grew a crop called Alfalfa. But in the USA they had too much Alfalfa, so they paid farmers NOT to grow it.
His father was paid not to grow it, and with the money he got he bought MORE land, so he could NOT grow Alfalfa on that land either.
So he got even more money, and bought more land to NOT grow Alfalfa. Soon he had thousands of acres, all not growing Alfalfa.
The soldier then used to say as a proud boast "My father is the biggest non-grower of Alfalfa in the country".
Wonderful humour.
