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."

Bulls Survive Tornado
There was a farmer who had a lot of live stock. He had
cows, horses, chickens, pigs, and bulls. One day a terrible
twister came and the man and his family were only saved by
throwing themselves in the nearest ditch. After it was all
over, he looked up to see that the house was gone. Saddened
by the loss, he went out to see if any of the animals had
survived. The horses, chickens, pigs, and cows were laid out
flat but the bulls were standing! The farmer was amazed and
asked them, "How is it that all the other animals are down
and you are still standing?" The bulls replied, "We bulls
wobble but we don't fall down!"
