Before there was President's Day, we had Washington's Birthday. Here in Washington, sales were for $22 (used) cars, 22 cent typewriters, and other absurd prices with "22" in them. I still have and occasionally use a Leica M3 (used) that I bought for $22 at a camera store's Washington's Birthday sale.

These days, it's just another excuse for advertising mattresses on sale. Sorry, no mistresses on sale.
