Leave it to America to take a family-friendly day in Ireland and make it over-the-top insane drinking fest here! We definitely love our green holiday, and have the t-shirts to prove it! But some shirts are not very work appropriate (or appropriate at all). Here are some funny but inappropriate shirts for St. Paddy's Day. They'll give you a giggle for sure, just make sure to don't let your boss see you wearing one! Slante!
