The next malefactor who received a dose of his own medicine was a fellow named Sinis, who used to ask passers-by to help him bend two pine trees to the ground. Why the wayfarers should have wanted to help in this activity is not disclosed. Presumably Sinis was persuasive. Once he had bent the trees, he tied his helper's wrists - one to each tree. Then he took a break. When the strain became too much, the victim had to let go, which caused the trees to snap upright and scatter portions of anatomy in all directions. Theseus turned the tables on Sinis by tying his wrists to a couple of bent pines, then letting nature and fatigue take their course.
