not exactly the copy to use answer but you can modify it to achieve your target

the html

 <p id="disclaimer">
    Disclaimer! This service is not intended for the those with criminal intent. Celebrities are kind of like people so their privacy should be respected.
  </p>
  <input type="button" id="toggleButton" value="toggle" />

the jquery

$(document).ready(function(){
$('#toggleButton').click(function(){
if($('#disclaimer').is(':visible')) {
  $('#disclaimer').hide();
} else {
  $('#disclaimer').show();
}
});
});
