"Rousseau's whoopee cushion"?
I thought it was Sartre's whoopee cushion!
to quote Mrs. Premise from Pythons: "Well, you know, a bit moody. Yes, he didn't join in the fun much. Just sat there thinking. Still, Mr Rotter caught him a few times with the whoopee cushion. (she demonstrates) Le Capitalisme et La Bourgeoisie ils sont la même chose... Oooh we did laugh."
But I thought that French de l'humour was supposed to be both "witty" and original! But even we have alread heard about certain "Power to the pretzel" T-shirts! These shirts are so 2003! I thought the french were more hip, more in tune with the "Zeitgeist" (excuse the Kraut word). Oh well..
