OK, this is really weird. A couple of nights ago, I had one of those strange, clearing-out-the-short-term-memory dreams that included prefab root beer floats, which of course is the kind of impossible creation that can only exist in dreams. Just think of the temperature considerations.
Now it turns out A&W has started selling exactly that. A&W promises it's a full root beer float experience without the "hassle," by which I take it they mean the overflow/spillage problem and the restrictions imposed by using real ice cream.
I can find no documentation on how they actually perform this magic or what that small-print "ice cream flavor" consists of, but I sense we have a new contender for most alarming "What's Inside" of the year.
