George W. Bush is sitting in a hotel lobby, planning his speech to a group of businessmen, when a man approaches him. "Excuse me, Mr. Bush, but my name is John Tapay, and I'm here with an extremely important client. We're going to see your speech tonight, and it would be a great help to me if when we walk by, you could impress him by saying, 'Hello, John'."
Bush readily agrees, and fifteen minutes later, the man walks by, deep in conversation with his client.

Bush waves and says, "Hello, John!"

The man replies, "Buzz off, Bush! I'm in a meeting," and keeps walking.
