Change wording of default thumbnail metabox

This is usually what I go with:

/** Use "Featured Image" Box As A Custom Box **/
function customposttype_image_box() {   
    remove_meta_box('postimagediv', 'page', 'side');
    add_meta_box('postimagediv', __('Set Dat Image'), 'post_thumbnail_meta_box', 'page', 'side');

}
add_action('do_meta_boxes', 'customposttype_image_box');

/** Change "Featured Image" box Link Text **/
function custom_admin_post_thumbnail_html( $content ) {
    global $post;
    if($post->post_type == 'page')
    {
        $content = str_replace( __( 'Set featured image' ), __( 'Upload dat Image' ), $content);
        $content = str_replace( __( 'Remove featured image' ), __( 'Remove dat image' ), $content);
    }

    return $content;
}
add_filter( 'admin_post_thumbnail_html', 'custom_admin_post_thumbnail_html' );
