Duke, it would be like a Limey wearing a Union Jack on the 4th of July IN THE UK. Now, if he did that in the U.S., that would be different.
Also, at least one of the students wearing a United States of America flag on their shirt in the United States of America on not-a-real-Mexican-holiday was, in fact, an American of Mexican decent.
Oh, and I like Taco Hell. I eat there about twice a week. It's hard to find decent food when you're a vegetarian and Taco Hell beans are meat-free. Triple Layer Nachos, Bean Burrito no onions and a water, $2.07 out the door. Where else can you eat for two bucks?
