A man, dying from thirst, was crawling through the desert. He crawled over a hill and sees a little bar surrounded by cars. He crawls in the front door and up to the bar. He chokes out the word, "Water!"
The bartender looks at him and says, "Got any money?"
The guy shakes his head no and again says, "Water!"
The bartender says, "No money, no water."
The guy looks around and spots a spittoon. He tells the bartender, "Guess I'll have to drink this."
The bartender replies, "Be my guest, no money, no water."
Customers see the man drinking out of the spittoon, start getting sick and start rushing out the door in droves.
The bartender gets alarmed and tells the guy to stop, saying he was just kidding. The guy keeps on drinking. By now the bartender is in a panic as the place is almost empty. He pleads with the guy to stop drinking.
As the last customer leaves the guy puts the spittoon down and wipes his mouth off. The bartender asks, "Why did you keep on drinking? I told you I was just kidding."
The man responds, "I couldn't stop."
"Why not?" the bartender asks.
The guy replies, "Cos it was all one long string!"
