Best frenemies Jon Stewart and Bill O'Reilly met for the umpteenth time on Wednesday's "Daily Show." The two zinged each other about Fox News, Stewart's upcoming directing project, and O'Reilly's prolific book production.

In the spikiest exchange, Stewart noted that Fox News has been feeling singled out by all the Justice Department's attention. He compared it to the profiling of Muslims by law enforcement. O'Reilly said that, after "14,000 acts of terror," it was necessary to track Muslims.

"I'm just doing the math here," he said. "If they keep mounting up, maybe you do a little profiling."

Stewart countered that there were around 30,000 deaths a year from gun crime. "Do you think we should start profiling ... the people with the guns?" he said. "It raises above your 14,000 incident threshold."

"What group do you want to zero in on?" O'Reilly said.

"Fox viewers?" Stewart quipped.
