What better way to tell somebody you love them than with the words of the great people of Pawnee? 'Parks and Rec' very generously shared these Valentine's Day greeting cards on their Pinterest, and we think they're swell. Tell somebody that you don't hate them, or even adore them, and if it gets weird just say "Hey, I'm sorry, I thought you LIKED that show." And then never talk to them again. Happy Valentine's Day!!
