ok, I guess I throw one out.. Beware! It's nasty.
This man has been walking through the desert for days and days without anything but the clothes on his back, which of course are ripped, torn and faded from walking in the desert for so long. He's literally dieing from lack of nutrition; no water, food, nothing. Eventually he comes across a desolate old town and see's a bar. Barely able to walk, he crawls in to the bar and is gasping for a drink.
"waahterr.. wahterr" pleads the man. A somewhat amused but hardley sypathetic bartender takes one look at the man and states, "Glass of water: five dollars!" Astonished at this, the man begins to cry, "I'll do anything, I don't want to die. Please, anything!" The bartender thinks about this for a minute and decides, "I will give you as much water as you want, if youuu.. drink from that spitoon" said the bartender, as he pointed to the spitoon in the corner.
The man hesitantly crawls over to the spitoon and lifts it to his lips. Thinking of his death, he immediately begins to drink, and drink.. and drink.. and drink until the spitoon is turned upside down over his head and empty.
The bartender burst out laighing, "OH MAN! I can't believe you did that! You didn't have to drink the whole damn thing!"
"I didn't have a choice," the man replied, "it was all one string."
