'92-year-old Tap Dancer': Casey Niestat's Tribute To His Grandmother Louise (VIDEO)

Here's a very sweet, very simple tribute from muck-raking NYC filmmaker Casey Niestat to his grandmother, Louise, a former Rockette who's been teaching tap classes out of her attic for forty-plus years. Niestat sets up a quiet profile of a devoted teacher, daughter and all-around grand dame. It's not bait for change, like Niestat's other films, but we'll eat all the hats in the office if "92-year-old Tap Dancer" doesn't inspire some spontaneous calls to grandmas.
