One day, God and Adam were walking in the Garden of Eden.
God told Adam that it was time to populate the world. "Adam", he said, "you can start by kissing Eve".
"What’s a kiss?", asked Adam.
God explained and then Adam took Eve behind a bush and kissed her.
Adam returned with a big smile on his face and said, "Lord, that was great! What’s next?".
"Now you must caress Eve".
"What’s caress?", asked Adam.
God explained and then Adam took Eve behind a bush and lovingly caressed her.
Adam returned with a bigger smile and said, "Lord, that was even better than a kiss! What’s next?".
"Here is what gets the deed done. Now I want you to make love to Eve".
"What is make love?", asked Adam.
God explained and then Adam took Eve behind the bush.
A few seconds later, Adam returned and asked, "Lord, what is a headache?".
