Question: One evening a man started to run. Then he turned left. Soon after, he turned left again. Then he started running home. When he got home there were 2 masked men waiting for him. Who were they?

Question: I have two arms, but fingers I have none. I've got two feet, but I cannot run. I carry well, but I carry best with my feet off the ground. What am I?

Question: I talk, but I do not speak my mind
I hear words, but I do not listen to thoughts
When I wake, all see me
When I sleep, all hear me
Many heads are on my shoulders
Many hands are at my feet
The strongest steel cannot break my visage
But the softest whisper can destroy me
The quietest whimper can be heard.
