Dropping JSON object on html page in asp.net mvc2

I'm using asp.net mvc2 and I want to drop some JSON objects from my controller similar to validation metadata. When we call Html.ClientValidation() before our form it drops some JavaScript on the page like

<javascript type="text/javascript">
    <!--CDATA[validation metadata]-->
</javascript>

I want to have some JSON objects dropped in my page that I can use through jQuery

<script type="text/javascript">
    var obj = <%= new JavaScriptSerializer().Serialize(new { foo = "bar" }) %>;
</script>

Now you can use the obj global variable:

alert(obj.foo);
