Ben Browder tells a story about being in acting school in England, and being in a class in which each student was to teach the others a dance style. The "good ol' Carolina boy" has done some dancing back home, and innocently pipes up, "I can teach the class to shag." The class, not surprisingly, doesn't react quite the way he expects. "No, really, I CAN!" doesn't help matters :-) Several of the guys in the class (including
http://en.wikipedia.org/wiki/Graham_Norton) are quite willing to take him up on his offer, and he figures out that British shag and American shag are 2 entirely different things ;-)
I can totally see Ben (or Cam, for that matter) doing the (American) shag :-)
