Happy St. Patrick's Day!

Phineas was wearing his green today.  He would like to wish everyone a happy St. Patrick's Day!  (Also, I would like to add that he did have on pants over this romper except when I was taking these pictures.  However, I would like to know if there really exists a place in the US where it is appropriate to wear such an outfit for a holiday that's in the middle of March.  I think I would like to live there someday.  Dreaming of summer...)
