Asking for Help

Somewhere in doctor's practice room, came a man ± 60 years old, a woman ± 25 years old and a child ± 2 years old.

After seated, there was a question and answer between doctor with these patients.

The Doctor : Who is sick ?
The Woman (who answered): That's Mr. Doctor, my husband can not move their weapons. (That's impotent).
The Doctor (half-surprised, because he thinks he's did her parents): "How long has the pain sir?"
The Man : It's been about 5 years ago doctor...
The Doctor : But your child  was ± 2 years old, that's impossible...

The Woman heard the question doctor did smile a little smile. The Man with a coy answer :

The Man : Yes, Doctor, that child is a child of my wife, but he's not my child.
The Doctor : Does your wife have time to marry when you're widowed?
The Man : No doctor, he was still a virgin.
The Doctor : So...!!?
The Man : That time... I asked for help to my neighbor because I want to have a child...

Hearing the unexpected answer before the doctor said :

The Doctor : Why didn't you ask me to do it ?

The woman heard the words of Doctor said, looking small smile full of meaning. Doctors soon realized, and correct it.

The Doctor : No...I mean...why didn't you seek treatment before !... XD
