This game is best played by a cohabiting couple. The couple can be straight, lesbian, bisexual, whatever, just so long as one spouse is absolutely knackered and the other one well-rested/full of beans. Game props: a. electric toothbrush with fully charged battery; b. house with a bathroom (ideally en suite or failing this, as near as dammit).
