1) I stand on one leg with my heart in my head. What am I?
--------------------------------------...
2) I have a mouth, I do not speak; I have four eyes, but cannot see; I have a bed, but do not sleep; Can you tell me who I be?
--------------------------------------...
3) What has six legs, two heads, four ears and two hands, and walks on four feet?
--------------------------------------...
4) I have a barrel without any beer. My sight is advanced, but I have no eyes. I have many chambers, but none are my home. What am I?
--------------------------------------...
5) He who makes me, makes me to sell. He who buys me does not use me. He who uses me does not know it. What am I?
--------------------------------------...
6) I speak when I am asked to, I always perform the correct role, I am punctual every day of my life, but everybody hates me. Who am I?
--------------------------------------...
7) I am lower with a head than without one. What am I?
