"What say you to a gorilla steak?"

"I'm told the niggers eat him. Don't they, Mak?"

"Yis, massa, dey doos. More dan dat, de niggers in dis part ob country eat mans."

Hah! This fantastically politically incorrect exchange comes from The Gorilla Hunters, by RM Ballantyne, and published in 1861.

For all this & more, I recommend you take in Iain Sharp's guide to Gorilla Lit (in the run up to a big ape movie, apparently) on Stuff: How to Keep a Gorilla., and Other Stories.
