Witch Doctor

A man had been troubled by his inability to achieve an erection.
After visiting numerous doctors and not getting any help he 
decided to consult a witch doctor. The witch doctor threw some 
herbs in the fire,shook his rattle,and danced wildly. 
When he was through he said,"I have placed a powerful spell 
on you, but it will only work once a year. When you are ready just 
say...1,2,3, and you will get the largest erection that you have 
ever had. After your wife has been satisfied she simply has to 
say,1,2,3,4, and it will be gone for one year." Later that night 
as the man lay in bed he said to his wife,"Watch this! 1,2,3!" 
His organ sprang to life,larger and stiffer than ever before. 
His wife was amazed,she smiled and said,
"That's great! But what did you say 1,2,3, for?
