Lauren tells her first joke!

Tonight at dinner, I heard Lauren mumble to herself, "Knock knock. Who's there? Ach." It took me a second to realize what she had just said! I'm sure she doesn't really realize what she said, but it was quite remarkable to Jen and I, and by the end of the night I could get her to say the whole joke, properly alternating lines with me. :) Knock knock. Who's there? Ach. Ach who? Bless you daddy!
