If you're single, make sure and pair up in the next 48 hours, otherwise you'll be painfully left out of June's newest holiday, National Breakup Day. True, it's not as festive as Open That Bottle Night, but it's still a great concept. So prepare yourselves to pour some drinks, cuddle up to that special someone and tell them how much they suck. Then kick them out the front door and immediately hit your favorite online hook-up site. You're free!
