Funny, Len! I had a student many years ago, he was about 22 at the time, who was a really nice guy, but clearly suffered from a lack of "cultural learning" -- the kind of information you just pick up along the way. He had a tremendous amount of U.S. geographic knowledge, which he learned in his favorite classes in elementary school - geography, so he was not incapable of learning. Part of my job was to teach him some of the important life information that he lacked. Buffalo wings was a part of that!! Yes, he knew chickens had wings, but these restaurants are serving up buffalo wings. He didn't know buffaloes have wings. And he wanted to know if I had ever seen a buffalo fly? It was so hard for me to keep a straight face; I quickly segued to talk about the buffalo statues which are along one of the NY Thruway exits to Buffalo. But he was completely serious.
