Pucker up, readers, it's National Kissing Day! The holiday actually originated in the UK to bring back the simple pleasure of kissing for kissing's sake, and then migrated over to the U.S. and Canada. So make sure to plant a big wet one on the special people in your life -- whether your lover, your mother, your barista or that guy who seems so grumpy on the subway.
In the meantime we have compiled some of the sweetest and steamiest lip-locks in art history. We're not quite sure if anyone can beat Gustav Klimt when it comes to crafting that perfect cinematic smooch but these other contenders get pretty close. Take a look and let us know your favorite kisses that we missed.
Happy National Kissing Day everyone!
