Don't mess with Texas!

When I visited the UN palace in February 2006 I took a guided tour with a small group of tourists. Some American, a couple of Australians, three Japaneses,...
There was also a couple of Texans in their 60, husband & wife. He wore the typical Texan hat, she was the typical American housewife. He looked like a modern cowboy in jeans, square shirt and cowboy hat and a little rude attitude. She was come out from a glossy magazine as the perfect 60 y.o. -but-still-young woman with a pastel tailleur and perfect manners. He carried around a canvas bag with the "don't mess with Texas" slogan, which I have never heard before but made me laugh. And he kept complaining he couldn't understand what the Asian guide was saying because whe was a foreigner and with a cold. I told him I was happy I was not the only one that didn't understand the guide - and that I though I lacked on English oral comprehension. He was polite and cool...a real Texan!!!! Now I really want something from the "Don't mess with Texas" campaign but the actual merchandising is pretty plan.
