Steve took his new wife camping for the first time. At every opportunity, he passed along outdoor- survival lore.
One day they got lost hiking in the deep woods. Steve tried the usual tactics to determine direction; moss on the trees (there was no moss), the direction of the sun (it was an overcast day).
Just as his wife was beginning to panic, Steve spotted a small cabin off in the distance. He pulled out his binoculars, studied the cabin, then turned and led his wife right back to their camp.
“That was terrific,” she said, impressed. “How did you do it?”
“Simple,” he replied. “In this part of the country, all TV satellite dishes point south.”
