A crazy guy jumps
onto a table in a
crowded restaurant
and starts
screaming: "I will
multiply you! I will
divide you!" People
scatter every which
way in a panic,
except for a little
old man in a corner,
who calmly continues
eating. The crazy
guy yells into the
old man's face,
again: "I will
multiply you! I will
divide you!" The old
man calmly replies:
"Go right ahead,
son. I am zero."
