Out at a country club I go to infrequently her in town, I'm standing outside talking to a gentleman I had seen dance before discussing dancing. I told him I couldn't dance and he responded "you were in the military, right?" yes. "well if you can do facing moves, you can line dance." he had assumed that I didn't know how to dance, but that was the funniest explaination of line dancing ever heard.
EDIT: 5/8/07: Ok since DD pointed this out to me, I have to fix it. For the record, I DO know how to dance, I am incapable of it due to one very destroyed knee.
