1.- What occurs once in a minute, twice in a moment and never in a thousand years?
2.- What goes up, but never comes down?
3.- I look at you, you look at me, I raise my right, you raise your left. What is this object?
4.- What goes around the world and stays in a corner?
...and the answers are:
1.- the letter m
2.- the age
3.- a mirror
4.- a stamp
