I have inadvertently invented a new type of alarm clock.
It is pretty cheap, but a bit cumbersome.
What you need to do is panic about being skint and sort through all of your books, videos and DVD’s to find some to sell on ebay.
Then pile them up in a dangerous pile and leave for three months (this is the cumbersome part, you have to set the alarm clock around three months before the day you want it to go off).

Come back, realise how skint you are and then tidy flat.
Then, at around 6am in the morning whilst you are asleep and after not being touched for three months the pile will fall over with a huge clatter, waking you up and scaring the living bejesus out of you.
Wake up, scream a little, realise what it was. Now you are awake.
Finally, roll back over and go back to sleep and be late for work (optional)
