A billionaire enters a reality show saloon with five bellboy hats, three red and two white.
“I need three volunteers to play a game for a million dollars,” he said. “Any takers?”
Three men put down their beer mugs immediately and volunteered: Jack, Tobias and Charlie.
“Very well. Set up three chairs in a triangle so each of you can see the other two,” commanded the billionaire.
This was speedily arranged.
“Close your eyes while I place one of these five hats on each of your heads. I’ll tell you when to open them. The hats are so small you won’t be able to see the color of your own hat,” he explained cheerily.
He put the hats on their heads and threw the remaining two out the window.
“I’ll give a million dollars to the man who can say which color hat he has on his head,” he said.
They opened their eyes and looked eagerly at their respective companions.
“What do you say, Jack?” asked the billionaire.
“Ummm, I don’t know,” Jack said with a sad face.
“What about you, Tobias?” asked the billionaire.
Tobias looked studiously at his two companions. “Well, I can’t say either,” he grumbled.
“But I know,” exclaimed Charlie jubilantly, “and I am blind.”
And, sure enough, he did know and received the million dollars with a big smile.
What was the color of Charlie’s hat, and how did he know?
