I'm not sure why, but about 1-2 times a month, the conversation at our dinner table is about wiggling ears. No kidding! Marc can do it. I can do it. Our kids cannot... yet. I guess it must be a bit like whistling and crossing your eyes and doing silly tricks with your tongue.
I am so happy to have found a GREAT article on ear wiggling. Check it out here: http://www.wikihow.com/Wiggle-Your-Ears.
