Talk about crossing the line!

Chris Rock appeared on The Today Show this morning to promote his new movie Top Five, but the comedian took his on-air opportunity to poke fun at the ongoing ratings rivalry between the show and GMA.

"Today Show, you guys are doing good. You got Ray Rice's wife on, man. You'll show Good Morning America. We got the wife on," Rock joked before taking things too far by referencing GMA host Robin Robert's much publicized cancer battle. "We'll show you Robin Roberts. Matt Lauer is going to get sick next," he added.

Yikes!
