   * You tear the punch card, despite the explicit warning on it that says, "Do not fold, spindle, or mutilate". The menacing robot stops pursuing you and grinds to a halt. Smoke trickles out of its chassis as it audibly breaks down. It begins to vibrate and wobble. One panel flies off and then another, and the robot begins ejecting cogs and gears at high velocity. Finally, the robot collapses entirely into a pile of greasy parts.
   * </pre>
   * <p>
   * <strong>Tear</strong> requires that the
   * {@link adventurejs.Tangible|Tangible}
   * {@link adventurejs.Asset|Asset} to be torn has
   * asset.dov.tear.enabled
   * set to true. By default, no special results will occur.
   * Authors wanting to make use of it may need to use a method such
   * as verb hooks. See
   * <a href="/doc/Verbs_PhaseHooks.html">Verb Phases</a>
   * to learn more.
