Two little boys are sitting in the living room, watching TV with their parents.

The mother looks over at the father with a wink and a nod toward the stairs to the bedroom.

The father "gets" the message, and they both get up and head towards the stairs.

The mother turns back to the two boys and says, "We're going upstairs for a minute. You two stay here and watch TV. We'll be right back, OK?" The two boys nod OK, and the parents take off upstairs.

The oldest of the two boys is old enough to know what's going on now, and he gets up and tiptoes upstairs.

At the top of the stairs, he peeks into his mom and dad's room and shakes his head disapprovingly. Back downstairs he goes, back to his little brother. "Come with me," he says, and the 2 little boys tiptoe up the stairs.

Halfway up, the older brother turns to the younger brother and says, "Now I want you to keep in mind, this is the same woman who used to bust our ass for sucking our thumb!"
