The best humor is unintentional, especially when it's on NPR's news shows, not normally a fount of laughter. During an interview of the dean of Regent University's Law School (the Christian school founded by Pat Robertson and attended by Monica Goodling and many other Bush Toadies), the interviewer asked how civil rights law is taught with respect to gay rights. The response talked about how they teach the Constitution, yada yada, and the cases as they stand, including Lawrence v. Texas, the sodomy case recently decided. The interviewer thought there might be a bit more to the story and responded "Is there a but at the end?"
Very unfortunate choice of words!
