Carl, the good dog, is in charge of the baby when Mommy leaves. He's a great babysitter. Well, he's a great babysitter if you want your baby to ride on the dog's back and swim in the aquarium and eat out of the cookie jar. Carl and Baby have one heck of a good time. Then, Carl carefully cleans up the mess and when Mommy gets home, all is well. It's darling.
