Jon Stewart does not like to be challenged. At least that's what Wyatt Cenac, a former "Daily Show" writer and correspondent, said in an interview with Marc Maron.

The story goes like this: During the 2012 presidential campaign, the Comedy Central show was angling to mock then-presidential contender Herman Cain. However, Cenac didn't like a fake "voice" being planned for a video of Cain. When Cenac brought up his concerns during a writers’ meeting, he recalled Stewart not being very happy and screaming to Cenac, "F--- off, I'm done with you," before storming out of the room.

Still, "The Daily Show" has had some pointed commentary on race in the U.S. in recent months. We dug up four of the best pieces.

The Death Of Michael Brown

When a grand jury decided against indicting a Ferguson, Missouri, police officer in the 2014 death of Michael Brown, tensions ran high across the country. However, Stewart pointed out that Fox News was defending the police officer while ignoring the death of the unarmed young man. When one Fox News guest said it was a matter of framing, Stewart agreed, saying, "White cop shoots unarmed black teen does sound terrible."

Grand Jury Decision On Eric Garner's Death

Shortly after the Michael Brown decision came another grand jury ruling in regard to the death of Eric Garner at the hands of the New York Police Department. Stewart took a sober tone, suggesting that while uncertainties remained in the Brown case, Garner's death was recorded on video and the facts were clearer.

On Rachel Dolezal

After it came to light that Rachel Dolezal, president of an NAACP chapter in Spokane, Washington, was white -- but claiming to be black -- Stewart again took on Fox News, which claimed the "transracial" concept was an element of liberalism. Stewart asked, "If being black is such a sweet deal, why are millions of white people ignoring this once-in-a-lifetime opportunity?"

Charleston Church Massacre

Striking a sober tone, Stewart said he was left speechless by the June 17 shooting at a historically black church in Charleston, South Carolina, that left nine dead. Comedy, according to Stewart, is tragedy plus time. So Stewart said he needed more time to find any humor in the situation. However, he pointed out that he'd prefer less tragedy.

Stewart's last appearance as host of "The Daily Show" is scheduled for Aug. 6. He will be replaced by Trevor Noah, who faced criticism over Twitter posts when his hiring was announced in March.
