Cheech Marin is one of the three finalists on the show. All the money won will go to charity.
"I'm playing for the Hispanic Scholarship Fund," said Marin. "It's the biggest Latino fund in the world. Their goal is to get every Latino in college. I am very honored to be able to contribute towards that."
Finalist Jane Curtin is playing for the U.S. Committee for UNICEF. She's been working with them for 25 years.
"It's basically a fund that UNICEF puts the money towards America," said Curtin. "We need help too.
And Michael McKean will play for the International Myeloma Foundation.
"It is time to make this disease rare," said McKean.
The three celebrities take the role of fundraiser seriously. But they can't help but have a good time.
"It's a competitive kind of thing. It's not pressure, its' a game," said Curtin. "It is for charity which is a good thing."
"Ideally you'd like to take home a bunch of money for charity, that's the aim. But we just try to keep it fun," said McKean.
So, what's the category that would keep it fun for these stars?
"Rock N' Roll of the 60s and 70s, yeah, I'd blow that out of the water," said McKean.
"I'd like fast food. I could ace that," said Curtin.
Watch the celebrities try to raise money for their charities on "Jeopardy" Thursday at 7 p.m. on ABC7.
