Thing One: This, from Julianne, cracked me up so bad.
Thing Two: A woman named Lauren Thompson dancing with herself, at four:
via Crooked House.
Think her influences might have included the Solid Gold dancers?
[Added later: I just rewatched and the four-year-old bit was filmed in 1987, so duh to me. At that point, I'm pretty sure the SG dancers had stopped filling all our lives with music and putting rhythm in our souls.]
