the doll

A man comes home with his little daughter, whom he has just
taken to work. The little girl asks, "Why do you call your
secretary a doll?"
Feeling his wife's gaze upon him, the man explains,
"Well, honey, my secretary is a very hard-working girl. She
types like you wouldn't believe, she knows the computer
system and is very efficient."
"Oh," says the little girl, "I thought it was because she
closes her eyes when you lay her down."
