An elderly couple was watching a Discovery

An elderly couple was watching a Discovery Channel special about a West African bush tribe whose men all had 24 inches long.

When the black male reaches a certain age, a string is tied around his  and on the other end is a weight.

After a while, the weight stretches the  to 24 inches.

Later that evening as the husband was getting out of the shower, his wife looked at him and said, ‘ How about we try the African string-and-weight procedure’?

‘The husband agreed and they tied a string and a weight to his.

A few days later, the wife asked the husband,‘How is our little experiment coming along?

‘Well, it looks like we’re about halfway there, he replied. ‘Wow, you mean it’s grown to 12 inches’?

‘No, it’s turned black.
