This 'joke' of Rock's was probably one of the lowest (imo). And not funny, in the least:
“Why are we protesting this Oscars? It’s the 88th Academy Awards, which means this ‘no black nominees’ thing happened at least 71 other times. You got to figure that it happened in the ’50s, in the ’60s. One of those years, Sidney [Poitier] didn’t put out a movie. I’m sure there were no black nominees some of those years, say ‘62 or ‘63. Black people did not protest. Why? Because we had real things to protest at the time. We were too busy being raped and lynched to care about who won best cinematography. When your grandmother’s swinging from a tree, it’s really hard to care about best documentary foreign short.”
Maybe this, then, is no surprise. (from deadline.com):
"The Oscars were all given out last night at the 88th Academy Awards but it turns out there is no gold, nor silver or bronze for ABC. With 34.3 million total viewers watching the Chris Rock hosted shindig from the Hollywood and Highland on Sunday, the Oscars took a tumble this year to hit an 8-year low."
