MY THEORY ABOUT HUMOUR
LEVEL 1
There is a banana skin on a path in London. A man walks down the street, stands on it and goes arse over tit.
This is funny. It is also predictable, logical and requires no thinking.
I will call this kind of humour "Benny Hill" humour.
LEVEL 2
There is a banana skin on a path in London. A man walks down the street, sees it, steps over it, then is savaged by a polar bear.
This is funny. However it isn't predictable, isn't logical and requires a little thought.
I will call this kind of humour "John Malkovich" humour. (As in the movie "Being John Malkovich")
LEVEL 3
There is a banana skin on a path in London. A man walks down the street, sees it, steps over it, then is mugged by Karl Marx and Friedrich Engels while they are discussing which drug to use in the phrase "Religion is the ----- of the people.
This is funny. However it isn't predictable, isn't logical, and requires some knowledge acquired beforehand to understand,
or it can act as a tool to educate the observer
I will call this kind of humour "Monty Python" humour.
eg; Ask me to name 10 philosophers and I can within seconds, because I know the Monty Python Philosophers song.
Level 1 humour the Americans are better than the British.
Level 2 humour the British are better.
Level 3 humour, I can't think of any American TV show or movie that even gets remotely near the likes of Monty Python, Blackadder or Yes Prime Minister. (please post examples if you can think of any)
To me Pyramids, and most if not all TP novels, are packed full of level 3 type humour. The Xeno's paradox, the Assassin's Guild or the riddle of the Spinx are just three prime examples.
Another Pyramids example
The camel is called You Bastard. Level 1 - camels are notoriously stroppy creatures.
The camel is the best mathematician on the Disc. Level 2 - this is completely illogical.
The camel actually does complex calculations involving vectors, phi etc. Level 3 - do you know what phi is?
(A little later I will test this theory to see how valid it is.)
