Frank: There was no party. We just smeared chocolate on your face and took the picture.
Marie: Frank!
Robert: What's he talking about, Ma?
Marie: Well, you see, dear, little babies really don't have any idea it's their birthday.
Frank: They're too dumb.
Marie: So we took a picture, so we'd have something to show you when you got older.
Robert: What about this picture of Raymond on his first birthday? Looks like he's having a party.
Marie: Well, of course, Raymond had a party.
Robert: What?!
Marie: Let me tell you what I learned about children, dear. See, with the first one, you might make a couple of mistakes. But if you're sensitive, you don't make the same ones with the second child.
