A man's off road vehicle breaks down in the middle of the Mojave desert.
It's the middle of summer and the area is not named "Death Valley" for
nothing, so he decides to hike out. By the time he finally reaches even a
dirt road, he is on his last legs and dying of thirst. Up ahead he spots a
roadside stand and a shack. He gets to his feet and stumbles up to the
stand.

"Water!" he croaks.

The guy at the stand smiles. "Hey, I don't sell water. My brother, he sells
refreshments in the shack next door. I sell ties. Wanna buy a tie?"

"No, I need water," the dying man says.

So he drags himself over to the door and the shack, hauls himself up on
his feet and starts to walk in, when the first man's brother stops him.

"Stop right there! Can't get in without a tie!"
