This reminds me of a funny situation.
A few years ago me and a buddy of mine from work started taking some Martial Arts classes. Of course we were both out of shape and were always sore after the classes.
Well one day at work, after a particuarly hard work out the night before, my buddy walks up to me and says:
" Man my ass is sore from last night, .....isn't yours?"
There was about 3 or 4 coworkers next to us with a horrifed look on their faces. Man, was that embarrassing.
