Carey is a supporter of libraries, crediting them for beginning his successful comedy career. On May 2, 2000, in a Celebrity edition of Who Wants to Be a Millionaire, he selected the Ohio Library Foundation to receive his $500,000 winnings. He later went on to win an additional $32,000 on the second Celebrity Millionaire, making him one of the biggest winning contestants on Millionaire who did not win the top prize. Carey also has played on the World Poker Tour in the Hollywood Home games for the Cleveland Public Library charity. In June 2007, Carey offered to donate up to $100,000 (in $10,000 increments) to the Mooch Myernick Memorial Fund if anybody could beat him at the video game FIFA Soccer 07 for the Xbox 360. He dared five players from both the U.S. Men's and Women's National Teams to compete against him. Carey ended up donating $100,000, plus $60,000 for losing two games out of the six games he played.
