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,
some asshole is bound to come up behind you and say,"Put that red nine on top of that black ten!"
