Get 4-5 pices of paper , print a nasty message on them , scrolling left to right or up to down ( use your imagenation ) , tape them togather with the ends loose ,feed them into a fax , dial the number of a telemarketer , then as the end comes out tape it to the tail , continous "FUCK YOU " untill the fax runns out of paper , or to REALLY mess with sombody make the background BLACK and type the mesage in WHITE , this will run the fax out of ink , or you Could do a mobious strip alternating from light to dark , again use your imagination
