When Oliver and Keith realised that their drinking was getting out of hand, they invented an ingenious, if not a little strange, way of cutting back. Instead of going to AA meetings, they sat at either end of a long table, and placed a glass of whiskey on the back of a tortoise and let it walk between them. If the tortoise would walk up to Keith, Keith would drink the content of the glass, if it would walk closer to Oliver, he would drink it, fill the glass again and set the tortoise in the middle of the table again. They reasoned this would slow their drinking down to a suitable level. Sometimes they would also turn the tortoise upside down and use it as an ashtray, or another time even as a codpiece. The tortoise became a weird but big part of their friendship.
