A boy of 6 years old never pays attention to his pant's zipper...which is always being left open. Because of this his mother often gets angry.

One day some of his relatives plan to visit their city, so his mother advised him that whenever she tells him to "close the Eiffel Tower", it means that he has to close his zipper.

His relatives arrive, and after some time, the boy asked his aunti, "Aunti, why did you come here?"

His aunti answered, "Dear boy, we came here to see the Eiffel Tower."

The boy said in great excitement, pointing towards his zipper, "But aunti, the Eiffel Tower is closed."

Aunti replied, "My boy, that is the small Eiffel Tower. I came here to see big one."

The boy answered politely, "Aunti, then I will have to call my dad."
