This is a nice one,,,

A young and arrogant pilot wanted to "show off" on the
aviation frequencies as he was approaching an airfield
during the night. So, he disregarded policy and, instead
of making an official request to the tower, he said,
"Guess who?"

The air traffic controller switched the field lights off
and replied, "Guess where?"
( Always do right , this will gratify some people and astonish the rest.!!)
