They may have us doubled up laughing as their hilarious, socially awkward characters in The Big Bang Theory, but this lovable group of nerds are far more socially equipped off-screen than their on-screen characters would care to admit. Standing up for the causes they believe in, they have each individually offered their fame to lend a helping hand to those they personally feel need it.
Jim Parsons - Sheldon
Parsons donated $300,000 to the Houston based, Catastrophic Theatre, where he performed many times early in his career.
Additionally, he has also contributed to the "Sound Off For Autism Speaks" fundraiser and is a Celebrity Ambassador for the charity Stand Up To Cancer:
Kaley Cuoco-Sweeting - Penny
Kaley started her own fundraiser to contribute to the 'The Humane Society of the United States':
"Baby seals are slaughtered every year as part of the commercial seal hunt in Canada, and I need your help to stop this cruelty. I am raising money for The Humane Society of the United States to help put an end to this unnecessary suffering, and every dollar you donate will go directly the Protect Seals campaign."
Simon Helberg - Howard
Rather than accepting gifts for his 30th birthday, Helberg asked his friends, family, and fans to donate to Save the Children instead:
“I didn't need a milestone birthday, like my upcoming 30th, to know how fortunate I am. I realize that there are so many children in the world who never see another birthday due to their unfortunate circumstances. This year, I decided the best way for me to make a “Big Bang” for my birthday is to give back. As I celebrate with my friends, family and fans, I have asked that instead of gifts, a donation be made to the Save the Children. The on-going support Save the Children provides for schools, teachers and the community overall, ensures many more Happy Birthdays for children all over the world."
Kunal Nayyar - Raj
Mayim Bialik - Amy
Mayim Bialik rapped alongside Reggie Watts and Right Said Fred to raise money for the charity One Kid, One World, which promotes education in El Salvador and Kenya. The track features on the comedy album '2776' and the proceeds go to the foundation.
