Mark Zuckerberg challenged Bill Gates then Justin Timberlake challenged US talk show host Jimmy Fallon. Barack Obama chose, as one can do, to avoid the challenge and donate to MND/ALS Research. Then there was Paul Bissennette...he took it to a whole new level. Andy Murray, and Rennae Stubbs, both great supporters of Laugh to Cure MND have taken the bath too. Now it's time for you to step up.If you haven't been challenged yet, or even if you have, join us this Friday, 22 August as we will be attempting a world record for the largest number of people simultaneously performing the Ice Bucket Challenge.
