this is possibly the most likely application of all
reminds me of a cruel prank I heard somehwere.
if you travel on the tube anywhere near the City (i.e. with lots of brokers on the train), then set your phone alarm to go off while you are deep underground, but change the alarm tune to an obvious ringing tone.
when it goes off 'answer' the phone and start talking loudly and pretend that you have just received amazing news that might affect the stockmrket, then start instructing the 'person' on the phone to start selling all your stocks immediately. Then look really pleased at the sudden offloading of all your stocks with a profit before the market crashes
End your phone call then watch the people around you frantically trying to get a signal on their phones.
