A friend has a three-year old who I'll call Kitty. Like a lot of kids, Kitty is very astute at catching her parents saying things they'd rather she didn't. For example, Kitty once heard her father say, “Yeah, and monkeys might fly out of my butt!” This made quite an impression.
Later, during a bowel movement, Kitty called her mom into restroom. “Mom, look, the monkeys are pushing it out!” she cried.
