A man asks his buddy

A man asks his buddy: “Listen to me! Why has your wife left you, if I may ask?”

And he says, “you know, she has told me that I am weak in the bed.”

“Oh, that is really sad. And what do you do to improve it?”

And he says again: “you know, I have bought one book, the name of this book is you know I am helping myself with the hand, I have learned all positions, but the last position I am not gonna make.”

“And what is the name of this position?”

“You know, imagine the missionary position.”
