Charlie Brown stands in Patty's doorway smiling as she exclaims,"Well, Charlie Brown!"

She waves him inside the house and says," Come on in...."

As he takes off his coat she continues,"Gee, it's good to see you...."

As they sit in chairs facing each other, she concludes,"If I knew you were comin', I'd have baked a mud-pie!"
