Without using an exploit to have this done automatically your only other choice is to settle for a mousefollow clickjack script, but this will be dependent on the user clicking somewhere on the page. There are 3 different ones in the first page of the Facebook section here, they just are not really worth the time to set up in my opinion as they will get your page banned or deleted and they have other flaws as well.
This comes up all the time and I bet there are a dozen different codes here on how to do this, but it doesn't work 1/100th as well as it used to.
Your best bet without having an exploit is to learn hjavascript basics, especially how the DOM works, then learn how to probe Facebook for XSS/CSRF vulnerabilities. If you are dedicated and serious you might find a vulnerability after searching for 6-12 months that you can use. It will probably get noticed, copied and will be patched by fb quickly, so if you find a way to do this give it all you got, you should be able to make $20k+ with it.
