Actor Charlie Sheen definitely isn't winning. On Thursday, he posted a racist tweet attacking President Obama for, of all things, engaging in a little March Madness.

After the president appeared on ESPN's SportsCenter to fill out his NCAA tournament bracket, which has become an annual tradition, Sheen lost it.

"Barry Satera Kenya u won't attend a soldier's funeral uhkros da street that u kild yet u have time 4 brackets? Sad c," the tweet read.

Sheen was referring to the funeral of Major Gen. Harold Greene, who was killed while serving in Afghanistan. Although then-Defense Secretary Chuck Hagel attended the funeral service, some conservative media outlets began spreading a myth that the White House didn't send any representatives to the two-star general's funeral, Media Matters reports. The lie was in response to news that three administration officials would be attending Michael Brown's funeral.

Sheen's rant elicited a number of humorous tweets in response that offered advice and warnings to not drink the bong water, to lay off of the cocaine, and perhaps most important, to stop being a racist.
