My father
is, for most of the year one of the quietest and most placid people you've ever met but for one day each year on the 1st of april he opens up and completely messes up at least one member of my family. Pranks have ranged from convincing everyone in my family they had jury duty over their holiday that year, sending me an itemised bill for £90 worth of porn sites I was supposed to have visited on a swanky internet terminal i had in my hospital bed after having my apendix out to convincing my nan Time Team were going to come and dig up her garden.
By far the best prank for longevity though has to be the time, 15 years ago, he meticulously cut open a cream egg with a hot knife, replaced the innards with mayonnayse, sealed it up, carefully rewrapped it and put it back in the frigde. My mum has not touched a cream egg since.
