A couple was watching a Discovery Channel special about an African bush tribe whose men all had manhood 24 inches long.
When males reach a certain age, a string is tied around their shaft and on the other end is a weight.
After a while, the weight stretches it to 24 inches.
Later that evening as the husband was getting out of the shower, his wife looked down at him and said,
โHow about we try the African string-and-weight procedure?โ
The husband agreed and they tied a string and weight to his willy.
A few days later, the wife asked the husband, โHow is our little tribal experiment coming along?โ
โWell, it looks like weโre about half way there,โ he replied.
โWow, youโve grown to 12 inches??โ
โNoโฆitโs turned black.โ
