According to the fun and silly holidays article in the Washington Post, Today is Put a Pillow on Your Fridge Day (May 29)! And it would be interesting to see how many people actually do this!

This weird holiday may be related to an old custom. In the early 1900s, putting a piece of bedsheet or nightshirt in the larder (food-storage cupboard) was supposed to bring plentiful food. After refrigerators replaced larders, the tradition shifted to pillows. Give it a try, and perhaps the fridge will be stocked with your favorite foods.
¡Pura Vida!
