How do you guys do that?

One day, while relieving himself in the employee restroom, Carl could not help but notice the unusually long penis on the black man in the adjoining urinal.

"How do you guys do that?" asked Carl. "I mean, get such long dicks?"

"Well," replied the black man, "when having sex, just push it in slow and pull it out quick. That exercises it."

After hearing this, Carl promised himself that he would try out this new dick-stretching technique on his wife. That night, Carl made love to his wife and tried the new method. Shortly after they finished, Carl asked, "Well dear, did you notice anything different about me?"

"Yeah," said the wife.

"You fuck like a black man!"
