The 'That '70s Show' co-stars reunited to see who was more knowledgeable about Hollywood trivia.

Ashton Kutcher and fellow That '70s Show alum Danny Masterson went on The Ellen DeGeneres Show on Wednesday to play "Pie Face." 

Kutcher was raising money for his charity Thorn, which builds software tools for law enforcement officials to help fight the sexual exploitation of children on the Internet. DeGeneres brought out his The Ranch co-star, Masterson, to compete against him in the game.

"Ellen said, 'Would you like to come on my show tomorrow and throw a pie in Ashton's face?,' but I see there are two holes," said Masterson about the game. "I feel like I'm getting Punk'd again," he added later on.

Kutcher joked his head didn't fit as they got settled into their respective places. Masterson seemed like he was in trouble when he didn't remember that DeGeneres hosted the Oscars in 2014, but it was really Kutcher that ended up with pie on his face after he couldn't guess the name of the O.J. Simpson prosecutor played by Sarah Paulson on The People v. O.J. Simpson.
