Another day, another celebrity showing their support for THON on social media. Actor Kal Penn tweeted a DonorDrive link Monday morning supporting the upcoming 46-hour dance marathon at the Bryce Jordan Center.

In 2 weeks, students @Penn_State (before you make the joke, yes, no relation ) are doing their annual 46-hour dance-a-THON to raise $ for a children's cancer hospital. You can donate a li'l bit here: https://t.co/aN0mhm2nSu

Penn is best known for his work acting in House and Harold & Kumar. He also worked as the White House’s Associate Director of Public Engagement under the Obama administration.

“Kal is a friend of a friend,” said Jonah Vitale, the student whose DonorDrive link Penn tweeted. “I just messaged him on Instagram and asked him if he’d like to donate to my donor drive page and he was all for it!”

Vitale is fundraising through the THON special interest organization Eclipse, which is one of the newest THON organizations.

“He was really excited that I was involved in THON and asked me when it was this year,” Vitale said. “He must’ve took it upon himself to tweet about it!”

Penn State and Four Diamonds quickly noticed Penn’s tweet, responding with their own thank you messages.

Thanks for spreading the word about @THON, @kalpenn! #FTK https://t.co/Am8L5H9JjH

Thank you for supporting @THON and Four Diamonds! Through donations, we ensure the families we treat for pediatric cancer never see a medical bill for their care. #FTK

This isn’t the first time Penn has engaged with Penn State students — he visited campus in 2008 before Obama’s first election to register students to vote.

“What a way to start off a Monday, am I right?” Vitale said. THON kicks off February 16 at the Bryce Jordan Center.
