Funniest/embarresing thing your kids have ever done?

I don't have kids of my own, but I do have a younger sister that I helped to raise. She was about 4 or 5 and was riding in the backseat of my car. We pulled up to a stoplight on a two lane road. The man in the car next to us was picking his nose. My sister yells out the window, "Hey mister, pick me a winner!" I was laughing so hard that the light turned green and I didn't even notice. Poor guy..lol.
