A man comes to a resort and wants to check into the hotel. The
hotel manager tells him that all their room are full.
The man doesn't believe the manager. He asks, "If the
president were to come here tonight, would be able to give him
a
room?" you provide a room for him?"
"Of course!" the manager answered.
"Then I am honored to tell you that the president will not
be coming here tonight. So you can give me his room!"
