Gilbert Gottfried's last Instagram post invited people to weigh in on "the slap."
The comic, whose family announced Tuesday that he died at the age of 67 after a long illness, .
Rock was slapped by Will Smith while presenting at the Academy Awards after Rock made a joke about Smith's wife, Jada Pinkett Smith.

Gotfried also shared the post on Twitter.
In a 2012 opinion piece for CNN, Gottfried defended fellow comics.
"If a comedian tells a joke that you find funny, you laugh. If he tells a joke you do not find funny, don't laugh. Or you could possibly go as far as groaning or rolling your eyes," he wrote. "Then you wait for his next joke; if that's funny, then you laugh. If it's not, you don't laugh -- or at very worst, you can leave quietly."
