Brain or muscles?
The strong young man at the construction site was bragging that he could outdo anyone in a feat of strength. He made a special case of making fun of one of the older workmen. After several minutes, the older worker had had enough."Why don't you put your money where your mouth is," he said. "I will bet a week's wages that I can haul something in a wheelbarrow over to that outbuilding that you won't be able to wheel back.""You're on, old man," the braggart replied. "Let's see what you got."The old man reached out and grabbed the wheelbarrow by the handles. Then, nodding to the young man, he said, "All right. Get in."

Atheist professor
An atheist professor was teaching a college class and he told the class that he was going to prove that there was no God.

He said, "God if you are real, then I want you to knock me off this platform. I'll give you 15 minutes!"

Ten minutes went by. He kept taunting God, saying, "Here I am God, I'm still waiting." He got down to the last couple of minutes and a big 240-pound football player happened to
walk by the door and heard what the professor said.

The football player walked into the classroom and in the last minute, hit the professor full force, sending him flying off the platform.

The professor got up, obviously shaken, and said, "Where did
you come from, and why did you do that?"

The football player replied, "God was busy; He sent me!"
