Ellen DeGeneres did her best to make Sandra Bullock, Anthony Mackie and Billy Bob Thornton as uncomfortable as possible in a round of "Never Have I Ever." In the game, the daytime talk show host and cast of "Our Brand Is Crisis" had to answer questions and reveal if they had or had not done something.

DeGeneres came out of the gate swinging and asked a racy question right away: "Have you ever had sex on the beach?" Thornton and Mackie both revealed they had, why Bullock said that she had never.

Mackie joked that he was "an awful person" as he said "I have" to most of the questions. He seemed particularly confused when Bullock said that she had never hooked up with someone in the back of a limo.

"What, you didn't go to prom?" he asked Bullock. "What did you do at prom?"

"I came home early because we broke up two weeks before," she said.

The truth telling was all for a good cause. For every question that the actors answered honestly, Shutterfly donated money to the Warren Easton Charter School in New Orleans, a school that Bullock works closely with and Mackie graduated high school from. In the end Thornton, Mackie and Bullock raised $15,000 for the school.
