Remember the rumors from a few years ago that Coors Light was going to release a beer can with a built-in shotgun tab on the side? It turned out to be completely false, but there's not really a good reason not to do it. It's not like not having one is preventing people from shotgunning, nor am I more likely to enjoy an aluminum can of Coors Light while reading Wordsworth by the fireplace simply because the tab isn't present. Besides, it's got to be a better can-technology innovation than a picture that tells me when something is cold. Isn't that what my hands are for?
