The best thing you can do for yourself and those around you is to just keep whatever it is you have to say to yourself until you leave your place of work. Nobody can do anything to you as long as you are not on company property and that is the best way to stay away from anything that can be remotely considered as sexual harassment. You might think it is funny to be annoying but the moment you are told to stop and you continue is the moment you will be in trouble.
