Our Winter Olympic gold medallist, Dale Begg-Smith, made his fortune through an internet business that delivers spam, viruses, trojans, hijackers and other malware to vulnerable computer users. His website (now taken down) brags about 20 million pop-ups per day. Oh and he also has a business flogging pop-up preventing software!
As someone who has wasted many hours ridding computers of these infestations, is it churlish of me to suggest the IOC Anti-Doping Agency test him for sampling his clients' wares? No blood or urine required: a 30cm ruler would suffice.
