Zoe does a "Christmas Story"

My daughter stuck her tongue to a metal hitching post in our yard, in sub zero weather. Her tongue will heal, and in the meantime, we're eating a lot of soft foods. Why, why, why would a child who has seen "A Christmas Story" do this? I think some people just have to lick the 9 volt batteries and touch the electric fences in life. She's one of them.
