A cannibal visited the witch doctor with a serious skin rash. The doctor gave him a small pot of grease to rub on. He returned next week completely cured. " Wonderful stuff what is it" he said "My best friend died . I boiled him in a pot for six days then skimmed the grease off" he replied. " What do you call it?" Said the cannibal. " Pal o' mine lotion" replied the witch doctor.
