A dear old man has been having trouble making love to his wife due to impotency.
He has tried pills, oils, anything he can get his hands on, but nothing works. He researched online, asked every online expert he could think of - to no avail.
He tells his buddy about this, and his buddy says "I know a witch doctor who has a remedy for this. Go see her, she will help you out.
The old man goes to the witch doctor and explains his problems.
"I know just the thing," she says, and hands him a potion. "Drink this. When you are ready, just say 'one, two, three.' Your problems will be solved. When you are finished, your partner must say, 'one, two, three, four,' and that will be that. You can only use this potion once every full moon."
Excited to try this new remedy, he makes his way home in a haste.
That night, things are starting to get hot and heavy. He turns around and says "one, two three." Just like that, he is hard as a rock, like he was 18 again. He faces his wife, ready to go.
Impressed, his wife stared at him and said, "Wow, that looks great. But what did you say 'one, two, three,' for?"
