Yes, March 1st is the day to celebrate the pig. It's a holiday around since the 1970s.
The purpose of pig day is "to accord the pig its rightful, though generally unrecognized, place" as an intellegent animal.
Among the many offerings of the pig the most memoriable song I can think of is Spam.
Well, there's egg and bacon
Egg sausage and bacon
Egg and spam
Egg, bacon and spam
Egg, bacon, sausage and spam
Spam, bacon, sausage and spam
Spam, egg, spam, spam, bacon and spam
Spam, sausage, spam, spam, spam, bacon, spam tomato and spam
Spam, spam, spam, egg and spam
Spam, spam, spam, spam, spam, spam, baked beans, spam, spam, spam and spam
Spam! Spam! Spam! Spam! Lovely Spam! Lovely Spam!
