Figure out why onload is called twice, get $42 (twitter.com)

  // HANDLE: $(function)
  // Shortcut for document ready
  } else if ( jQuery.isFunction( selector ) ) {
    return rootjQuery.ready( selector );
  }

Calling jQuery(fn) twice will trigger the .ready() call twice. Apparently they are stepping on each other.

It's been solved http://twitter.com/atmos/status/8350201154
