Day 13 got off to an appropriately unlucky start for the housemates when they were roused from their peaceful slumber by a piercing whistle.

The unpleasant morning wakeup call - signifying the housemates should throw on their Cub Scout uniforms and parade in the garden - came at precisely 08.50 am, before which point nothing but snores had resounded around the bedrooms.

The housemates, aware of what a little minx Big Brother can be, may well have anticipated such an early morning disturbance. So a split second after the whistle rang, bodies flew around in search of woggles, while unidentifiable screeches of "Out Of Bed!" pierced the air.

Canny Cub Scout Jon realised bashing together in the dark was fruitless and screamed for luminosity, "Lights! Hit The Lights!"
