HURRAH FOR MISLEADING HEADLINES! ... still... in 2015... "Porn
   sniffing"? REALLY? But... this dog _can_ sniff out mass storage
   devices as small as an SD card.
   I'm actually surprised it wasn't done sooner. Having worked with
   computers my whole life, I know the smell of electronics. I
   mean, I don't SNIFF them... you just know the smell. it's not
   "food". It's not "an old sock". It's electronics; they have a
   smell. Now I'm don't have a wall-penetrating sense of smell like
   this dog here; I can't smell a USB stick in a drawer but it
   makes sense that a dog can be trained to smell them.
