A brave explorer was once exploring a jungle in Africa when he was captured by a tribe of cannibals. The cannibals, however, were fond of problems in logic, and they said to the explorer,
"We are going to allow you to make one statement. If the statement you make is true, we will burn you alive at the stake. If the statement you make is false, then we will boil you alive in a huge pot of water."
The explorer, however, was very clever. He made a statement, and the logic-loving cannibals were forced to let him go. What statement did he make?
Suddenly he heard someone call out, "Wait!". He turned to look back and an elderly woman was standing there with her hands behind her back. She wanted to ask him one more question to really prove his cleverness. "I have some flowers behind my back, and they're yours if you know how many I have."
Her riddle was this: "All of my flowers except two are roses. All of my flowers except two are tulips. All of my flowers except two are daisies. How many flowers do I have?".
Again the explorer, such a smart man, answered correctly and went on his way, new gifts in hand. What did he say to the elderly lady?
I got both of these from this site, and I merged them together, they are not my own.
