McHappy Day is one of Australia's longest running charity events and it's coming up again this Saturday 14th November.

McHappy Day is the annual fundraising event for Ronald McDonald House Charities (RMHC) which aims to brighten the lives of seriously ill children and their families. In 2009, McHappy Day is aiming to raise $2.5 million for Australian families and your help is needed to ensure that this years' McHappy Day is the happiest yet!

With many of Australia's favourite personalities lending a hand, head to your local McDonald's restaurant on November 14 and you could be served your Big Mac by one of a host of well known celebrities. $1 from every Big Mac sold will go directly to funding RMHC programs, with proceeds from Byron Bay Cookies, McHappy Day Wristbands and Crazy Straws also going to RMHC.
