The Rosses
The Rosses were the family that the 5 year old Karl Pilkington stayed with when his parents went on holiday. In order to deal with Karl's high energy level, the Rosses would place their large and ferocious cat on top of him while he was sleeping, making him scared to move. Ricky laughingly called this "a cat paperweight, to keep Karl in place". His experiences with the Rosses was used as an example by Karl himself of his non-normal upbringing.
They were mentioned in the 15 March 2003 show.
