I used to think that the "Mattress Sale" phenomenon every President's Day was inexplicable. But then came the Clinton administration.
After that story emerged, I did some research, and realized that Kennedy, FDR, LBJ, and especially Warren Harding lived up to the mattress sale concept too.
Not to mention the immortal Thomas Jefferson. Just ask his thousands of descendants.
So, in honor of our many presidents, Happy Mattress Day to one and all.
