After creating heaven and earth, God created Adam and Eve.
And the first thing he said was, "Don't".
"Don't what?" Adam replied.
"Don't eat the forbidden fruit." God said.
"Forbidden fruit? We have forbidden fruit? Hey, Eve...we have forbidden fruit!"

"No way!" says Eve
"Yes way!" says Adam
"Do NOT eat the fruit!" said God.
"Why?" Adam and Eve both ask.
"Because I am your father and I said so!" God replied, (wondering why he hadn't stopped creation after making the elephants).

A few minutes later, God saw his children having an apple break and He was ticked!
"Didn't I tell you not to eat the fruit?" God, as our first parent, asked.
"Uh huh," Adam replied.
"Then why did you?" said the Father.
"I don't know," said Eve.
"She started it!" Adam said.
"Did not!" said Eve.
"Did too!"
"DID NOT!"

Having had it with the two of them, God's punishment was that Adam and Eve
should have children of their own.

Thus, the pattern was set and it has never changed!
