A group of nuns who lived in a convent way out in the bush, were out and about one day when they came upon an old bicycle. Thinking that it would a nice way for the nuns to get some regular exercise, the Head Nun allowed the bike to be taken back to their convent. In time, all the Nun's had a chance to use the bicycle and it soon became quite popular among all of them. Indeed, it became so popular that the head Nun had to draw up a schedule so all the nuns could have a chance at using the bike. Very soon, however, much quarrelling began whenever someone rode the bicycle outside of their rostered time or if someone else rode it for longer than was necessary. Seeing how much fuss the bike was causing, the Head Nun called a meeting and said to all her flock: "Sisters, I would expect you all to be more controlled about the bicycle. If I hear of any more bickering I'll have no choice but to put the seat back on."
