Four of us on holiday in Egypt, three waiting in the lobby of the hotel for Ian to join us from his room.  As time went on, I offered to go up to see what was delaying him as Michele was losing patience. 

He opened the door with a smile and sheepish grin.  "Come on in" he said.  Then, grinning even more, he said quietly that he had been sitting on the loo and his eyes alighted on the bidet next to him; curious as usual, he wondered what the taps actually did, so he twisted one as far as it would go - nothing - so he tried the other, with which a powerful jet of water hit the ceiling, showering him and the entire bathroom!  He had some cleaning up to do before Michele found out, plus needing to change completely.  I couldn't stop laughing.  This could only be my brother!
