A man is walking through the Sahara desert dying of thirst shouting 'water, water' to nobody at all. 'Water, water' he continues, until finally he finds a cluster of different pastel coloured tents.
He wonders to himself if it's one of those mirages he's heard about, or is it simply the relentless heat of the merciless sun, pulsating on the top of his head, sending him crazy.
Anyhow, he decides to carry on and see what happens and to his delight they are real! He crawls into the fist tent saying 'Water, water, please give me water!' "Sorry" came the reply, "we only have jelly and custard here" so he staggers into the next tent and cries 'Water, water, please give me water!' "Sorry" came the reply, "we only have jelly and custard here"
This goes on with same reply in every tent until he comes to the very last one. 'Water, water, please give me water' he croaked, 'for heaven's say I'm dying here'.
To his delight they have some and the man says "Please don't drink it too quickly, it'll make you sick". 'No problem' he replied, 'Thank you so much you have saved my life. All the other tents only had jelly and custard, I can't believe it!'
"Well" came the reply, "It is a trifle bazaar"
