dont ever do that with your mobile phone.
my friends picked up a mobile phone in school (poly) one day and
there was a home-made video of this couple doing it, seperated into
several short clips for fast forward convenience. the girl was CMI
however 
during breaktime, we found ourselves sitting at the nearby
playground, watchin the video all over and over again, memorizing
their faces... trying to recall..etc.. we're still trying to locate
the couple in school, hopefully able to pass their video back to
them.
