A man crawls out of the desert...

...and into a small village which has some market stalls in the street...
He crawls up to the first one. 'Water, water! Give me water!' he cries. 'I'm sorry,' says the first stallholder, 'I only sell custard.'
The man crawls up to the second stall. 'Water, water! Give me water!' he cries. 'I'm sorry,' says the second stallholder, 'I only sell cream and sponge.' The man then crawls up to a third stall. 'Water, water! Give me water!' he cries.
'I'm sorry,' says the third stallholder, 'I only sell hundreds and thousands.' 'I can't believe no one has any water,' says the man. 'I know,' says the stallholder, 'it is a trifle bazaar.'
