I've always wanted to but never have

Have you ever had a boss or coworker you can't stand?  There's probably not a single person that can honestly answer that with a no and if you do say no, i bet you never had a job.  Careerbuilder.com launched a viral ad campaign that allows you to send anonymous emails to your boss or coworkers.  Here's the website in case you're interested http://www.anonymoustipgiver.com/

I think this is a particularly dangerous time (for boss's that is) to give employees the ability to honestly speak their minds.  I mean, how many times have you wanted to blow up when your boss strolls in at 4:45 with a new project he needs finished by morning.  The worst part is you know he's not going to read for at least a week.  I can't tell you how many times i have looked a coworker squarely in the face, smiled and said thanks when all i really wanted to say is, "really?  it took you how long to figure that out?  Did you really just ask me that?  I CAN"T BELIEVE THEY PAY YOU MORE THAN ME!"  

Not that i would ever do this but theoretically you could send an email to your boss using the service and try to make it sound like it came from a coworker you don't like and hope your boss thinks it's him/her.  muah ha ha...that would be evil...
