Used to watch the Pythons back in the 70s. My Dad was in England during WWII (pre-Normandy) and told me that a lot of G.I.s never got 'British' jokes. They would go to the music halls for entertainment. I have always gotten the jokes and the comic bits.
Oh,yea, the G.Is didn't like the beer over there. It was too dark, too thick and was served warm (with a hot poker) during the winter.
As the Brits would say of the American soldier....."Over paid, over sexed and over HERE!"
