A guy is lost in the desert. He sees someone in the distance, so he staggers up to him and pleads, ''Water! Water!''
The other guy says, ''I don't have any water. I'm a tie salesman. Do you want to buy a tie?''
The first guy just repeats, ''Water! Water!''
So the tie salesman says, ''About an hour that way, over that dune, there's a restaurant that has water.''
The first man staggers off in that direction. About four hours later, he returns, crawling on his hands and knees. He's sunburned and near death, crying, ''Water! Water!''
The tie salesman says, ''I thought you went to the restaurant. You didn't get any water there?''
And the thirsty guy says, ''They wouldn't let me in without a tie.''
