When I saw you I fell in love. And you smiled because you knew.
Status: Not by Shakespeare
Although often attributed to Romeo and Juliet, Shakespeare aﬁcionados the world over can assure you that neither this line, nor anything like it, appears in that play. It doesn’t even sound like Shakespeare. It is by Arrigo Boito, who does at least have a Shakespeare connection in that he’s written a number of operas based on Shakespeare’s work including Othello and Falstaff.
