Think December 2003 - the England rugby team's open-top bus ride through London to celebrate winning the 2003 RWC in Australia. Full of its own self-importance, awash with MBEs, entertained at Buckingham Palace and fêted at Downing Street, the England rugby team has never fully recovered.
Think September 2005 - the England cricket team's team open-top bus ride through London to celebrate winning the 2005 Ashes series (at home, no less). Full of its own self-importance, awash with MBEs and fêted at Downing Street the England cricket team has never fully recovered.
Think May 2005 - the Welsh Rugby team were joined by 20,000 fans, the Prince of Wales and the Duchess of Cornwall in the Millennium Stadium to celebrate winning the 2005 Six Nations Grand Slam. Full of its self-importance, the Welsh rugby team then endured 2 highly mediocre Six Nations campaigns in 2006 and 2007 before being dumped out of the 2007 Rugby World Cup by Fiji, failing even to make the quarter finals.
Think 26th May 2008 - and the Welsh Rugby Union's announcement that a free music party is being thrown at the Millennium Stadium for fans to celebrate the 2008 Grand Slam. The party will include The "As long as we beat the English" Stereophonics, X-Factor failure Rhydian Roberts, Shaun Edwards' ex-girlfriend Heather Small and rent-a-Welsh-voice Katherine Jenkins. Expect, at the very least, a sobering hammering at the hands of South Africa to follow next month.
Think Ireland, wondering whether it might have been a good idea to celebrate their 2006 and 2007 Triple Crowns after all.
And think Scotland, wondering whether they'll ever have anything to celebrate again.
