In a live performance of Tracy Morgan, audience groaned after he use R word.

Tracy was actually joking during his last weekend performance in New York, saying

"Don't ever mess with women who have retarded kids." The audience groaned, but Tracy didn't stop: "Them young retarded males is strong. They're strong like chimps."
About 3 weeks ago, tracy apologised for his joke gay joke which his co-star Tina Fey didn't like.Morgan joked that he would stab his son to death if he spoke in a "gay voice."

In his apology, Morgan said,

 "I want to apologize to my fans and the gay & lesbian community for my choice of words at my recent stand-up act in Nashville."

"I'm not a hateful person and don’t condone any kind of violence against others.", added by Morgan.

Sometimes you just gotta slow down from your jokes right? Earlier this year, he was also caught unguarded when he was to chose between Tina Fey Or Sarah Palin? and he answered

“let me tell you something about Sarah Palin, she’s good masturbation material.”
