"What’s a kiss?", asked Adam.
God explained and then Adam took Eve behind a bush and kissed her.

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?".

"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?".
