Well, some modern-day genius has finally invented the Doozy. Basically, it is a combination of a koozie and Croakies. You put it around you neck, you put your can or bottle in it, and you're good to go.
As ridiculous as this concept is, it really is pretty practical, especially once tailgating season rolls around. While you're grilling, now you don't have to find a place to put down you beer. If you're playing an intense game of cornhole, you have both hands free to help nail your throw. They're available in a variety of colors, and custom printing options are available so you can buy one for everyone in your office. You can get them for cans or for bottles.
A camo one is available that would certainly come in handy in the dove field.
Additionally, a "We Are Alabama" bottle version is available, with all of the proceeds going towards recovery from the tornadoes earlier this year.
The can versions are only $5.99 and the bottle versions are $6.99. These seem like a great price, and they're cheap enough to pick up a couple since your friends will inevitably try to steal them. Your Yankee friends will probably think they're stupid, but those of us from the South will get it.
