While we are taking the mickey out of Americans, here's a story I read on a business travel forum. The poster was in Business class next to a Texan couple flying from a US airport to Frankfurt on Lufthansa. The steward came round with the meal service and got chatting with the Texans:
Steward: "So where are you going in Germany?"
Texan: "Oh, we're going to Munich for a holiday. We went to Munchen last year and enjoyed it so much we thought we'd go again but somewhere different."
Steward: "Oh yes, I was brought up in Munich; it's a nice city. But don't you know Sir, Munich and Munchen is the same place!"
Texan: "Is is?" (To wife) "Gee Honey, looks like we messed up again. Oh well, I'm sure we'll have a great holiday anyway!"
Steward: "Well never mind that.... how about some of this caviar?"
Texan: "Caviar? Cay-viar? What's that?"
Steward; "Oh, you know.... fish eggs."
Texan: "Okay. Give me two!"
The story concludes with the teller saying that the steward rushed to the galley and could just be heard through the curtain stifling hysterical laughter with his face buried in a towel.
