I wonder why this holiday is not publicized so much!?

I've  never heard my boss  say..."Hey don't forget, tomorrow is National Goof Off Day, so everyone can wear pajamas to work!" Or "Come in an hour late" or anything of the sort. So, I'm not sure it's actually an Official Holiday!

But none the less March 22nd is National Goof Off day cause it says so here!

So how will you spend the day? Has your boss ever let you celebrate this day?
