Found this interesting...It's from the wikipedia page about the Banshee "This comb detail is also related to the centuries-old traditional romantic Irish story that, if you ever see a comb lying on the ground in Ireland, you must never pick it up, or the Banshees (or mermaids — stories vary), having placed it there to lure unsuspecting humans, will spirit such gullible humans away."
...Don't pick up the comb it's meant to mislead you!
