It transpires that the theorist of the Proptestant work ethic was a right laugh when he was pissed:
It transpires that as a young professor Weber ‘suffered from obsessional thoughts and, especially after nights of drinking, sometimes imagined for the whole day that he was Jumbo the elephant and lived in a zoo’. This was fairly often because ‘alcohol-tinged male company, even without deeper friendships, seems to have been what excited him par excellence’. According to those who knew him best, there was ‘a quite elemental kind of sociability in Weber: he was a buddy with all his soul, a buddy for the moment thought capable of creating happiness; a drinking pal, a song mate, an accomplice in furious story-telling and boasting’.
I suppose you could argue that there's a Protestant Drink Ethic going on here. At any rate, he really seems to have worked at getting drunk and then playing the big-I-am with all the 'furious story telling and boasting'. And none of it seems to have had much to do with pleasure.
