Washing our hands...and armpits.

Okay...so I understand that Scarlett would imitate us lathering soap up in our hands. She sees Joe and I do this all the time. But where the heck did she get the armpit thing from?! It cracks me up. She does it every time. We haven't bought the "Elmo Washes His Armpits" DVD yet, so I can't blame Sesame Street. Well...I guess I can't complain about her having good hygiene.
