A little before last Christmas, a New Zealand mom named Christine Burnie was standing in line at the hardware store when a man came up to her to talk about her backside. That's sadly common when a lone woman is out trying to buy drywall screws or anything else home-improvement related. What's uncommon is that the guy was actually being helpful! He wanted to let Burnie know that she had a black mole on her back that should get checked out by a doctor immediately, which would be a very weird pick-up line.
