Is it possible to inject a jQuery script into a page if the page isn't already using jQuery? We have a few pages in our sites where we don't add jQuery if it doesn't need it, but I'm using it to automate the page with WebDriver. I don't want to test my JavaScript on every browser just for these pages. 

Example usage of jQuery code:

```
public static long GetLongValueViaJQuery(IWebDriver driver, string jQueryCode)
{
    IJavaScriptExecutor js = driver as IJavaScriptExecutor;
    return (long)js.ExecuteScript("return " + jQueryCode);
}

```
