Yesterday was jokingly declared "National Smack a Bum Day" in Dublin, Ireland, but some people missed the joke. Some folks got excited and began posting the images to Twitter. Soon enough, #NationalBumSmackingDay was trending worldwide. Though it's unclear if any spirited groping took place, hopefully people are a little more apprehensive in the future. Otherwise "National Smack a Bum Day" might lead to lawsuit or injury.
