say bock!

On the ride home from shopping this morning, Gretchen & Carl were singing "Old McDonald Had A Farm". Gretchen was singing and would supply the animal, then Carl would add the noise. It was very cute! I even got to chime in and say "snake" and he did the sound! But, he wasn't fast enough with the response to Gretchen singing "and on his farm he had a chicken" and Gretchen had to loudly prompt him, "Say bock!!"
