My dad always told us that he was Elvis. When we were little, we weren't quite sure, because there was more than a passing resemblance. Plus, my dad, who never, ever sang, would belt out Elvis songs every time we expressed skepticism.
Among them, Blue SUEde shoes.
As further evidence that he was Elvis, he would offer up that none of us had ever seen the two of them in the same room together. Pretty compelling evidence ... when you're six!
