Bill Maher's built a career around controversial statements about those two subjects polite Americans aren't supposed to talk about: politics and religion.

Have a taste: Back in 2001, shortly after the September 11 attacks, Maher stated that he disagreed with President George W. Bush after the president called the terrorists were “cowards.” Maher responded by saying that “[the US military] have been the cowards, lobbing cruise missiles from 2,000 miles away. Staying in the airplane when it hits the building, say what you want about it, it’s not cowardly.”

This remark got his Comedy Central show Politically Incorrect with Bill Maher cancelled. Lucky for him, HBO gave him a platform in 2003, with Real Time with Bill Maher.
