How can I refactor this jQuery code?
<p>The code below is for a simple newsletter signup widget.</p>

<p>I'm sure there's a way to make it more concise, any ideas?</p>

<pre><code>var email_form = $('.widget_subscribe form'); 
var email_submit = $('.widget_subscribe .submit');
var email_link = $('.widget_subscribe .email');

// Hide the email entry form when the page loads
email_form.hide();

// Show the form when the email link is clicked
$(email_link).click( function () {
 $(this).toggle();
 $(email_form).toggle();
 return false;
});

// Hide the form when the form submit is clicked
$(email_submit).click( function () {
 $(email_link).toggle();
 $(email_form).toggle();
});

// Clear/reset the email input on focus 
$('input[name="email"]').focus( function () {
    $(this).val("");
    }).blur( function () {
     if ($(this).val() == "") {
      $(this).val($(this)[0].defaultValue);
     }
});
</code></pre>
