A girl went to the doctor with her knees all cut up.

The doctor said, "What happened to your knees?"

She replied, "It's from making love doggie-style."

The doctor asked, "Don't you know any other position besides doggie style?"

She said, "Yeah...but my doggie doesn't."

One day, an African chief's wife gave birth to a white child and the chief was absolutely stunned. He suspected some hanky panky and went to the white Jesuit missionary father and looked at him suspiciously.

"You have been having sex with my wife," he accused the white father, who looked very uncomfortable.

The Jesuit, attempting to wriggle out of the difficult situation explained Mendel's laws of genetics to the wrathful black man.

"You see that herd of sheep," he said pointing to the chief's herd, "Most of them are white; but you will also

notice 2 black lambs among them."
