A pregnant woman goes to the doctor

... and she is worried about all the tasks she won't be able to do. She asks the doctor if she is still able to wash dishes. He tells her yes. She asks if she can still walk the dog. The doctor again tells her yes. Then she pauses for a moment. The doctor thinks he knows what she is about to ask. The woman starts to speak and says, "Doctor, my husband was wondering---" the doctor interrupted her and told her that yes, sex was still permissible and would not harm the baby. The woman looks at him and says, "No doc, my husband was wondering if I could still mow the grass."
