NATIONAL YELLOW PIG DAY HISTORY

Our research found National Pig Day originates sometime during the early 1960s. Two mathematicians by the name of Michael Spivak and David Kelly were analyzing the random properties of the number 17 and a mysterious yellow pig. It seems the process became excessive and professional. Kelly gave lectures and taught classes around Yellow Pig, and Spivak made publications in several mathematics texts. While not based upon it, Spivak does subtly reference the number 17 and Yellow Pig.
