I'm loathe to re-gurgitate someone else's re-gurgitated story on the Net, but this one is too good to let go unacknowledged. The voice of the London Underground, Emma Clarke, was recently let go from her job after 'management' discovered she was keeping a personal blog of spoof Underground announcements.
Listening to her MP3's will evoke much chortling, I guarantee. A few of my favourites:
"We'd like to remind our American tourist friends that you are almost certainly talking too loud."
"Would passengers filling in answers on the Sudokus please accept that they're just crosswords for the unimaginative and are not in any way more impressive just because they contain numbers"
"Do not drop litter on the train. Please use the tramps provided"
