28 April 1986, Atlanta (GA) Journal and Constitution, “English, the language of success” by Chet Fuller, pg. A8:     
If black folk ran the highly successful chain of toy stores known as “Toys R Us,” according to a popular joke, they would call it “We Be Toys.” Funny joke. At first. Then comes the stinging aftertaste.
