When I was a youngster we believed that the Queen had an official apologiser, who would traipse a few paces behind Her Maj. Every time she dropped one, the apologiser would have to cough quietly and say: "Terribly sorry, ma'am".
We reckoned it was a crappy job - after all, you couldn't keep it for long. Once the next lot of invitations came around to Buck House, there would be a little scrawl on the bottom: "Would be gr8 to CU and Phil the Greek, but don't bring that farting oaf again, there's a luv - he made the place pen and ink something chronic."
What is it about farting and the royals, though? Kaiser Bill was apparently obsessed with farting and bottom jokes, while a courtier at the court of Good Queen Bess is said to have gone into self-imposed exile for years after farting in front of the Queen (...sorry, didn't know it was her turn - very old joke!).
When he finally re-appeared all those years later, the first thing Betsy said to him was: "Worry not, Sir Philip; we have quite forgot the fart!"
