html select - jQuery - disable selected options

Need to disable already selected options in select box using jQuery. I'd like it to grey out like asmselect.

Test my example here.

//JS
$("#theSelect").change(function(){          
  var value = $("#theSelect option:selected").val();
  var theDiv = $(".is" + value);

  theDiv.slideDown().removeClass("hidden");
});


$("div a.remove").click(function () {     
  $(this).parent().slideUp(function() { $(this).addClass("hidden"); }); 
});

//HTML
<body>
<div class="selectContainer">
    <select id="theSelect">
        <option value="">- Select -</option>
        <option value="Patient">Patient</option>
        <option value="Physician">Physician</option>
        <option value="Nurse">Nurse</option>
    </select>
</div>
<div class="hidden isPatient">Patient <a href="#" class="remove" rel="Patient">remove</a></div>
<div class="hidden isPhysician">Physician <a href="#" class="remove" rel="Patient">remove</a></div>
<div class="hidden isNurse">Nurse <a href="#" class="remove" rel="Patient">remove</a></div>
</body>?

UPDATED: Here's the finished solution. Thanks to Patrick and Simen.

Add this line to your change event handler

    $("#theSelect option:selected").attr('disabled','disabled')
        .siblings().removeAttr('disabled');

This will disable the selected option, and enable any previously disabled options.

EDIT:

If you did not want to re-enable the previous ones, just remove this part of the line:

        .siblings().removeAttr('disabled');

EDIT:

To re-enable when you click remove, add this to your click handler.

$("#theSelect option[value=" + value + "]").removeAttr('disabled');
