This hilarious St Patrick's Day greeting card is just what you need for a few good laughs this Saint Patrick's Day. Three Irish potatoes are headed to the pub, where they plan on enjoying a nice pint. McDonald's Pub seems like as fine a place as any, but that sign looks awfully familiar. We all know what McDonald's is famous for, don't we? Needless to say, these three potato friends are somewhat... changed when they finally emerge, green beer in hand. This rib-tickling ecard is sure to make your friends and family chuckle as the newly transformed friends have a chat to acquaint their new selves as a lively jig plays over the end of this delightfully fun St Patrick's Day card.
