The humble Post-It note has a lot to answer for. The conduit of many an office gag, how many of them are actually used for proper messages? Very few, we're willing to bet. We've taken things a step further and devised some memo notes that will suit your mood without the need for a flash of divine inspiration.

These fifty pre-printed memos will allow you to rule the office and intimidate fellow workers without so much as lifting a biro. And after all, isn't intimidation what working life is all about. Just leave one of your 'I'm busy now, can I ignore you some other time?' notes on a subservient desk and watch as they squirm, knowing full well that you are firmly in control of things in office land.

Other uses include leaving them on the bosses desk with someone else's name signed at the bottom. It'll be a P45 festival before they know what's hit them. That's the trouble with bosses, you see - no sense of humour.
