I got delayed for 15 minutes at Waterloo tube station this morning - ordinarily an exasperating experience - until the station announcer gave the following explanation (I tried to note it word for word..) :
"We apologise for the delay, we were told there was a body on the line, but it turns out, it was a shoe ..."
Obviously it was a woman who called the "emergency" in, given that they put the life of a shoe above all else - "But officer! It had sparkly straps and everything!!"
