National Month For??

I think someone set up months to celebrate unusual things because they got bored one day and just came up with unusual things to celebrate.  I don't think people actually celebrate them because most people don't know of these unusual things.  Three things that are celebrated in May are Mother's Day, American Bike Month, and National Nurses Week.  One thing I would like to celebrate in this month is National No Shoes Day because it would be cool to see everyone walking around with no shoes.
