One, Two, Three
After a few visits with the psychiatrist, the psychiatrist confesses he can not figure out what is wrong. The psychiatrist decides to refer him to a witch doctor.
The witch doctor says, "I can cure this!" He throws some powder on a flame, and there is a flash with billowing blue smoke. The witch doctor says, "This is powerful healing, but you can only use it once a year. All you have to do is say '123' and it shall rise for as long as you wish."
The guy then asks the witch doctor, "What happens when it's over?"
The witch doctor says, "All you or your partner has to say is '1234' and it will go down. But be warned it will not work again for a full year."
The guy goes home and that night he is ready to surprise his wife with the good news. So, as he is lying in bed with his wife he says "123", and suddenly he gets a massive erection.
With that, his wife turns over and says, "What did you say '123' for?"
