Query: Niggers Come In All Colors

Dick Gregory's autobiography is a book you will finish in one night because you won't put it down! You will also find yourself re-reading most of it for the remainder of your life. But "Nigger" is just the start of something much bigger. Gregory became arguably the greatest man who has ever lived. Tune into his website ... in conjunction with ordering and reading some of his books available from amazon.com. Mr. Gregory made a lot of mistakes during his childhood and as a young adult, but he found something inside himself that helped to change the world. Junior high school is a perfect time to begin reading this book. "Nigger" is funny and provocative. Gregory uses humor to get his message across in a one of a kind way. It should be required reading for ALL junior high and high schools.
