Sean Penn is angry that South Park creator Matt Stone suggested that the US would have better leaders if lazy and apathetic voters chose not to vote. Matt Stone and Trey Parker lampoon Sean Combs’ Vote Or Die in "Team America: World Police."
Penn wrote: "I do mind when anybody who doesn’t have a child, doesn’t have a child at war, or isn’t or won’t be in harm’s way themselves is saying that ’there is no shame in not voting if you don’t know what you are talking about’."
Penn adds that the lives of innocent people in the world are at stake in this election. He signed the letter with a four letter expletive. Stone and Parker say they were "howling with laughter" after reading the letter.
