Chris Rock invoking the late Nicole Brown Simpson didn't land with the public, and it's definitely not landing with her family either -- 'cause he's getting dragged by them.
Tanya Brown, Nicole's sister, tells TMZ ... CR's crack wasn't just unfunny, it literally doesn't make sense. She says equating getting slapped at the Oscars to a gruesome double homicide is apples to oranges -- so, she thinks it's lacking in logic and a basic connection.
With that said, Tanya tells us his attempt at humor was distasteful to say the least, and offensive to the extended family .
