I'm betting it was Spaw letting one off in there... and I don't mean a stick of dynamite!

I've used them but only when desperation (or pregnancy) demanded. The only good thing about them is that there is plenty of elbow room (unlike most public cubicles), but there is always the feeling that the doors will open at the wrong moment or that the passing public outside can hear every fart, grunt and sigh of relief!
