I've found that a spaghetti server is a great tool for scratching my back. We have one in the kitchen for food and different one on a shelf elsewhere. Of course, children like to copy their parents so 6 year-old Luke scratches his back just like his Dad, which I find rather endearing.
But sitting at the dinner table a few nights ago, he went very quiet, his eyes widened and asked "Dad, why is your back scratcher in the pasta?".
Just because two things look the same, they aren't necessarily the same.
