Rock teaching Brandon how to dance to classical music.
Rock playing in a box and singing the best line of Row, Row, Row Your Boat (that would be the "Merrily merrily merrily" part).
Rock getting Fix to draw "nomber M" (another M) "rye-dare" (right there) on his paper. He is FINALLY learning to correctly identify some colors. Although if you ask him "What color is this?" nine times out of ten he'll say "bee-u" (blue).
