Once when picking up a date I needed to use the facilities. It was a 'MAYDAY!' situation. I did so and returned to the living room to continue polite conversation. The bathroom was close to the living room and my position on the couch was close to the hall. An unmistakable smell began to waft it's way past my nose and a little more than embarrassed I excused myself, went into the bathroom and...no fan! So, I opened the window a crack and left the door shut, but it was too late. As I walked back into the living room the area was permeated with the foul(to anyone but me, anyway)odor. Needless to say there wasn't a second date and this is the first time I've confessed this foul deed to anyone!
