Head of a Whale
Riddle:
The head of a whale is sixfeet long; his tail is as long as his head and half his body, and his body is half of his whole length. How long is the whale?
Oh, how I love my dancing feet!
They stay together - oh so neat.
And when I want to walk a line,
They all stay together and do double time.
I count them up, ten times or more,
And race on-off, across the floor.
A magician is standing on a concrete floor holding a raw egg with his hand outstretched.
Without the aid of any other objects, he is able to drop the egg 2 feet without breaking its shell.
How did he do it?
I have two arms, but fingers none. I have two feet, but cannot run. I carry well, but I have found I carry best with my feet OFF the ground. What am I?
