(I babysit several kids, and because they're not mine, I never share their names in the internet. So, please bear with me as I call them Boy(age 3 1/2) and Girl(age 4).)
Today, a friend came over and was laughing at Girl's pigtails. He said, "You know what's under a pig's tail? A pig's hiney." Boy put his hands on his hips and said, "Don't talk to my girlfriend like that! She's special!"
