"I Don't Speak Egyptian"

My kids and I were talking about something at the end of reading group one day this week. Honestly, I can't remember what we were talking about. One of my little girls was being silly. She said something. I guess I responded that I didn't understand what she was saying. She said, "I don't speak Egyptian." I was like, "What? Egyptian?" I have NO idea where that came from, but I laughed on what came "Out of the Mouth of Babes."
