Found on the Football 365 forum, this absolutely wonderful Larry David moment:
Friend of a friend was staying with friends in a chalet in a French ski resort, really nice place, white carpets etc.
He comes down off the mountain really needing a shit. He thinks, "I'll just go straight back and do my business there" so he goes back to the place as fast as possible. He gets in, realises he needs to go badly, and so runs into the nearest loo, which happens to be the parents (owners') bathroom.
He does a massive shit and feeling satisfied with himself, stands up and presses the flush button. nothing happens. he panics, tries everything, lifting off the lid, nothing works, no water ...
