To apply or not to apply...

When one finds a killer job with great benefits, does one apply or no? I'm debating whether or not to jump ship at my current job (hourly and doing grunt work) that I've been at for less than 48 hours for a more interesting and lucrative position. Does she or doesn't she? Or does she apply without telling anyone and see what happens? If you're bright, you can guess what this girl is going to do tonight.
