"The Fall" joke

A man named Jack was walking along a steep cliff one day, when he accidentally got too close to the edge and fell. On the way down he grabbed a branch, which temporarily stopped his fall. He looked down and to his horror saw that the canyon fell straight down for more than a thousand feet.
He couldn't hang onto the branch forever, and there was no way for him to climb up the steep wall of the cliff. So Jack began yelling for help, hoping that someone passing by would hear him and lower a rope or something.
"HELP! HELP! Is anyone up there? "HELP!"
He yelled for a long time, but no one heard him. He was about to give up when he heard a voice. "Jack, Jack, can you hear me?"
"Yes, yes! I can hear you. I'm down here!"
"I can see you, Jack. Are you all right?"
"Yes, but who are you, and where are you?"
"I am the Lord, Jack. I'm everywhere."
"The Lord? You mean, GOD?"
"That's Me."
"God, please help me! I promise if you'll get me down from here, I'll stop sinning. I'll be a really good person. I'll serve You for the rest of my life."
"Easy on the promises, Jack. Let's get you off from there; then we can talk. Now, here's what I want you to do. Listen carefully."
"I'll do anything, Lord. Just tell me what to do."
"Okay. Let go of the branch."
"What?"
"I said, let go of the branch. Just trust Me. Let go."
There was a long silence.
Finally Jack yelled, "HELP! HELP! IS ANYONE ELSE UP THERE?"
