HALF A BUBBLE OFF CENTER 

not all there, mentally speaking. A couple of sentences short of a paragraph, a few shards of pottery short of a full anthropological theory, a few wafers short of a communion, one's belt doesn't go through all of the loops, one's driveway doesn't quite make it to the road...I THINK YA GET THE PICTURE!
