a man was walking in the desert one day and was so thirsty , he thought he was going to die, he trekked on until he eventually found a tiny village. He walked up to the first man and asked for some water. the man replied no but he would give him a tie. The thirsty man retorted " im thirsty! what good is a stupid tie!" he continued on until he stumbled upon a restaurant. he asked the man on the door if he could have some water. the doorman replied certainly, but you will need a tie to enter.
