BTW, I had the same thing happen on WC #7
If I may, this reminds me of a joke I heard back in 1985/86, as told by the 1986 world snooker champion Dennis Taylor (who is from Northern Ireland, so this isn't being racist against the Irish)...
Paddy was leaving Ireland to go work in London, England. As he was leaving, Mrs Dunn from next door asked Paddy, "Would you mind looking up our Neale and ask him why he doesn't write home. He lives in WC1." (The 'e' on the end of Neale is also pronounced, so sounding similar to 'nearly'). "I will Mrs Dunn", said Paddy, and off he went. Paddy arrived at the airport in London, and as he was making his way through the corridors he saw a sign which said "WC". He went inside and saw numbers on the doors. He walked down until he came to no. 1. He knocked on the door and a voice inside said "Who is it?". "Are you Neale Dunn?" asked Paddy. The voice from inside replied "Yes, but I haven't got any toilet paper". Paddy replied "Well that's no reason not to write to your mother".
(In case anyone isn't aware, WC's are toilets - Water Closet).
