The best one I got from the local high school lately: didn't even dawn on her that it may not be the smartest thing skip last period and go swimming, then show up for work in a wet bathing suit.
Her tits popped clean out when she bent to load paper in the copier and stood up again.
Of course I didn't fire her.
Had to call her at home and tell her to get over her embarrassment quickly, and come back. There were crowds of guys wanting to copy their grad books next day.....
