It was a dreary, rainy, icky day today, so Suzi and I were taking it easy, laying on my bed and watching Dora. After a bit, she turned to me, knocked on my arm and said, "Knock, knock, mommy."
Delighted, because I didn't know this was a skill she yet possessed, I ask, "Who's there?" "Orande," she tells me with a big smile.
"Orange who?" "ORANDE!" she squeals in delight, having gotten me but good.
We go through the joke about 18 more times, and I keep trying to work "Banana" in there too, but she just didn't see the comedic need.
Then she knocks on my arm again, "Knock, knock!"
"Cat," she says with a sly little smile.
Rubbing her cheek against my arm, she delivers the most perfect punchline I've ever heard: "Meooowww!"
Pretty sure I've never laughed harder in my life.
