'You can't teach an old dog new tricks' -- so the saying goes -- and Tracy Morgan appears to be one roughed up pup. The comedian and actor, who recently went on an apology spree after a barrage of hateful homophobic comments he made during a Nashville stand-up show, has done it again -- this time slamming the mentally and physically disabled.

"Don't ever mess with women who have retarded kids," he said at a recent stand-up show in New York, according to the New York Times. "Them young retarded males is strong. They're strong like chimps," he quipped before continuing with a joke about a 'crippled' teen girl he was allegedly once romantic with.

It's no surprise the the 42-year-old comedian is a proponent of controversy, his vulgar and often offensive stand-up shows are nothing new -- and that's exactly the reason he sells tickets, right? So why the hullabaloo surrounding Morgan's homophobic, sexist, ignorant and often downright cruel 'jokes' now?
