h2g2 The Hitchhiker's Guide to the Galaxy: Earth Edition

Tuttys was a stationary supplier in Hull many years ago and they used to produce an occasional but incredibly boring newsletter. The objective of the game was to secrete the Tutty's newsletter on your workmates person, or in a file on their desk, or any other spot where they weren't likely to immediately spot it. Often a cry of anguish would go up from the office when some hapless soul found themselves unexpectedly in possession of the dreaded newsletter. Then a new round would begin.

The now bedraggled newsletter is nearly 20 years old and the game is still going strong - I'm the last of the original contestants still working (and I'm old enough to know better) but a new generation has emerged to keep the game alive.
