It's Empty
 

It's Empty

Little Susie, a six-year-old, complained, "Mother,
I've got a stomach ache."

"That's because your stomach is empty," the mother
replied. "You would feel better if you had something
in it."

That afternoon, her father came complaining that he
had a severe headache all day.

Susie perked up. "That's because it's empty," she said.
"You'd feel better if you had something in it." :11:
