Mum and Dad have gone out and left me at home all by myself. Normally I would be making prank phone calls, setting up buckets of water over half-opened doors and putting rubber snakes underneath pillows – but not tonight. Tonight I’m standing on a ladder polishing the light-globes in the loungeroom with Dad’s CD cleaning cloth. Don’t tell me. I know what you’re thinking. You’re thinking, Andy, if your parents really have gone out and left you all alone, why are you wasting precious practical joke preparation time polishing light-globes? Why aren’t you making prank phone calls, setting up buckets of water over half-opened doors and putting rubber snakes underneath pillows? Well, the reason is that tonight I’ve decided to clean up the house as a surprise for Mum and Dad. I’ll admit, it might seem a bit unusual to polish light-globes, but the trick to making a place look really clean is in the details.
