Lines
One day, there was a catastrophic event that caused all humans on Earth to die. To sort things out, everyone went to Heaven. God came in and said,
"I want the men to make two lines.
One line for the men who ruled their women on Earth and the other line for the men who were ruled by their women. Also, I want all the women to go with St. Peter." With that, the next time God looked, the women were gone and there were two lines.
The line of men who were ruled by their women was 1000 miles long, and in the line of men who ruled their women, there was only one man.
God became angry and said, "You men should be ashamed of yourselves. I created you in my image and you were all whipped by your mates. Look at the only one of my sons who stood up and made me proud. Learn from him!
Tell them, my son, how did you manage to be the only one in this line?"
The man replied, "I don't know, my wife told me to stand here."
