In honor of the anniversary of the release of "...And Justice For All", it's Metallica shirt day.

The idea is for you to wear your favorite Metallica shirt, snap a picture of you in it and post it with the tag #MetallicaTShirtDay.  The web guys at Metallica.com will be going through the tags looking for proud wearers to include on the website.

It gets even better. If you don't have a Metallica shirt to wear, you can click here to put yourself in a shirt digitally. Don't forget that tag, the guys are looking to feature you!

Also, don't forget to vote in "Master Of Puppies" right now for Metallica tickets.
