THE INDIAN WITH ONE TESTICLE

There once was an Indian who had only one testicle, and whose given name was Onestone. He hated that name and asked everyone not to call him Onestone. After years and years of torment, Onestone finally cracked and said, "If anyone calls me Onestone again I will kill them!" The word got around and nobody called him that anymore. Then one day a young woman named Blue Bird forgot and said, "Good morning, Onestone." He jumped up, grabbed her, and took her deep into the forest where he made love to her all day and all night. He made love to her all the next day, until Blue Bird died from exhaustion. The word got around that Onestone meant what he promised he would do. Years went by and no one dared call him by his given name
until a woman named Yellow Bird returned to the village after being away. Yellow Bird, who was Blue Bird's cousin, was overjoyed when she saw Onestone. She hugged him and said, "Good to see you, Onestone." Onestone grabbed her, took her deep into the forest, then he made love to her all day, all night, all the next day, all the next night, but Yellow Bird wouldn't die!
