A salesman telephoned a household, and a four year old boy answered…

Salesman: May I speak to your mother?

Boy: She’s not here.

Salesman: Well, is anyone else there?

Boy: My sister.

Salesman: O.K., fine. May I speak to her?

Boy: I guess so.

At this point there was a very long silence on the phone. Then…

Boy: Hello?

Salesman: It’s you. I thought you were going to get your sister.

Boy: I tried, but I can’t get her out of the crib!
