A Scout Master was teaching his boy scouts about survival in the desert.

"What are the three most important things you should bring with you in case you get lost in the
desert?" he asked.

Several hands went up, and many important things were suggested such as food, matches, etc. Then one
little boy in the back eagerly raised his hand.

"Yes Timmy, what are the three most important things you would bring with you?" asked the Scout
Master.

Timmy replied: "A compass, a canteen of water, and a deck of cards."

"Why's that Timmy?"

"Well," answered Timmy, "the compass is to find the right direction, the water is to prevent
dehydration..."

"And what about the deck of cards?" asked the Scout Master impatiently.

"Well, Sir, as soon as you start playing Solitaire, you can be sure someone is bound to come up
behind you and say, "Put that red nine on top of that black ten!"
