It seems that when the Lord was making the world, he called Bill over and bestowed
upon him twenty years of normal sex life. Bill was horrified.
"Only twenty years of normal sex life?" But the Lord was very damant, that was all Bill could have.
Then the Lord called the monkey and have him twenty years. "But I don't need twenty years," he protested, "ten is plenty for me." Bill spoke up eagerly, "Can I have the other ten?" The monkey graciously agreed.
Then the Lord called the lion and gave him twenty years, and the lion, like the monkey wanted only ten. Again
Bill spoke up, "Can I have the other ten? The lion said of course he could. Then came the donkey and hewas given twenty years, but like the others, ten was sufficient and againBill pleaded, "Can I have the other ten?" The donkey said yes he could.
This explains why Bill Clinton has twenty years of "normal sex life", plus ten years of monkeying around, ten years of lion about it, and ten years of making an ass of himself.
