I recall an old story of Vince Lombardi, coach of the Packers:
During half-time, after a poor showing, the Packers sat... and sat... and sat in the locker room waiting for the expected scolding from Lombardi. With 5 minutes before the 2nd half started, coach Lombardi finally showed up: "Oh, sorry, I was looking for the MEN"S locker room, sorry ladies" and left. The Packers went on to win the 2nd half!
