One of the countless things that the Internet has introduced is the rampant abuse of the exclamation point. Before blogs, IMs, and message boards, the "."-to-"!" ratio was something like 100-to-1.

function invert_bool($val){
  if($val == true)
    return false;
  if($val == false)
    return true;
}
