An American man, a Russian man, and an African man were all up in a hot-air balloon together. After a few minutes, the Russian man put his hand down through the clouds. "Aaah!" he said. "We're right over my homeland."

"How can you tell?" asked the American.

"I can feel the cold air." he replied.

A few hours later the African man put his hand through the clouds. "Aah we're right over my homeland." he said.

"How do you know that?" asked the Russian. "I can feel the heat of the desert."

Several more hours later the American put his hand through the clouds. "Aah, we're right over New York."

The Russian and the African were amazed. "How do you know all of that?" they exclaimed.

The American pulled his hand up. "My watch is missing."
