Tracy Morgan just can’t seem to watch his mouth. The comedian performed at Caroline’s in New York City and is under attack again for cracking offensive jokes, this time targeting the mentally disabled.

Don’t ever mess with women who have retarded kids,” Tracy said during his set, reports the New York Times. “Them young retarded males is strong. They’re strong like chimps.” 

The Arc, an organization that works with people with intellectual and developmental disabilities, has criticized Tracy’s comments. “Tracy Morgan should apologize immediately,” CEO Peter Berns told E! News. “This quote is far too offensive to be excused as comedy, and it is very hurtful to people with intellectual and developmental disabilities and their families,” Berns said.

This is the second time this month that Tracy has been urged to apologize for offensive remarks. He came under fire for making homophobic comments during a stand-up act in Nashville. When will Tracy learn his lesson?
