Bristol Cancer Help Centre is the UK's leading holistic cancer care charity, specialising in the world-famous Bristol Approach to cancer care that works hand in hand with medical treatment to support people with cancer and their families.
The charity, whose patron is HRH The Prince of Wales, have now put up personalised pants to raise funds in their "Star Draws" auction, each pair with a reserve price of £50 ($80).
Along with his signature, Martin Johnson has added the phrase "Don't soil these pants" whilst his Leicester team-mate Neil Back writes "Hurt, Pain, Agony … Love it!" on his.
Meanwhile, Simon Taylor's have a large Superman sketch on the crotch area, Brian O'Driscoll's has rugby balls drawn in a suitably predictable region whilst Dan Luger has gone for the simple autograph.
Other rugby personalities to put chip in with some pants are Bill Beaumont, the Newcastle Falcons squad and former Wales scrum-half Robert Howley whilst the likes of Victoria Beckham, Jamie Oliver, Rolf Harris, FatBoy Slim, Gary Lineker and Linford Christie are just some of the other stars to lend a hand.
