So you think that humour was invented in the 1980's? If that's true, the tv-shows from 70's, like Fawlty Towers or even The Benny Hill show, are going to look quite bizarre in my eyes. I personally think that there were rational livings on earth already before I was born - even hundreds of years ago. The Don Quijote was published 1605 and it is not a science or religious book ;)
