It seems that when the good lord was making the world,he called man aside, and bestowed upon him 20 years of a good sex life. Man was horrified but the creator refused to budge. Then the lord called the monkey and gave him 20 years."But I don’t need 20 years,"said the monkey.“Ten is plenty.” Man spoke up and said:“May I have the other ten years?” The monkey agreed. Then the lord called on the lion and gave him 20 years. The lion too, only wanted 10. Again man asked if he could have the other 10 and the lion agreed. Then came the donkey who was also given 20 years.Like the others 10 years was enough for him. Man again asked for the other 10 years and the donkey gave it to him. This explains why man has 20 years or normal sex,10 years of monkeying around, 10 years of lion about it and 10 years of making a jackass out of himself.
