National Peanut Butter Cookie Day

A couple of days ago, the world celebrated the National Peanut Butter Cookie Day.  I didn't know there is such a day until a few days ago when I was gifted with some homemade cookies by a friend and she told me what was the special occasion.  I didn't realise that the cookie could have it's own national day.  I really thought this day was usually reserved for and celebrated by countries with significant events in their history.  Well I guess the modern world has made celebrating much more interesting.
