Football (Premiership, World Cup, Champions League, FA Cup), Rugby (6 Nations), and Cricket. Don't mind tennis (wimbledon), golf (Augusta), snooker (World Championship), cycling ( Tour de France), athletics (Olympics), The London Marathon, London Boatrace, Grand National Horseracing, Grand Prix...the list goes on. I'd eventually get to the Superbowl, the world series baseball, basketball and Darts. The list is unending so apart from football I only have time to watch major events.
However nothing touches the World Cup with England to win in Germany 2006.
