Celebrate Pi Day and St. Patty’s Day on both March 14 and March 17 with just one very cool Pi-rish Party Shirt. Kiss Me I’m Pirish features a green shamrock complete with Pi symbols and the dates 3.14 and 3.17. In this economy it certainly makes sense to buy a party shirt like this. Who can afford to buy two shirts for holidays that are celebrated within three days of each other during the same month of March? Thanks for supporting Mudge Studios.
