Lying in a hospital bed, Mr. Clarke whispers to his wife, "He's a n****r! I don't want no n****r doctor!"
"Sweetheart, can't you give it a rest. He is no different than you are." his wife responds.
"Mr. Clarke, you have lost a lot of blood and are going to need a transfusion." the doctor says as he approaches the bed.
"Bet they even have black blood! Don't want no black blood!" Mr. Clark mumbles under his breath.
As he hangs up a bag of blood, the doctor retorts, "It's all red... and they also have great hearing!"
