Ya wai. It has a mind of it's own. Here is an all too familiar scenario: You're sitting in the waiting room of the orthopedic center. You are surrounded by old ladies and old men with various bone and joint problems, when suddenly, you pop a boner FOR NO APPARENT REASON. And then...well, then, my friend, the nurse callsyou. You stand up, and WHAMMO. Nasty glares from old ladies are shot at you, and one of the old guys is smiling at you. True story.
