Another "Where Did You Learn That?!?!"

The other night, I took Lauren to eat at McDonald's. We were on the run from one activity to the next, so quick and easy ruled the day. Before I took her to order, I needed to change her diaper. I had her up on the changing table in the McD's bathroom and she was looking up at the pictures that comprise the safety information. All of a sudden, she said, "It's like Rock, Paper, Scissors, Mama." I swear I did a double take. Where in the world did she learn that?
