Swimming Trick

A fun trick is to go to your local community swimming pool with a whole load of weights hidden in your swim trunks and then go to the high dive and pretend to jump off, but really just throw the weights into the water and everyone will get splashed and then wonder who splashed them and not see anyone surface so they think that the person is drowning and they will go down there to look for him but they won't find him because they think they are looking for a really fat guy, but since you are the only one that knows what is really going on you can jump in to the rescue and grab some other random dude and be the hero.
