Lawyer and a Doctor (Impaired of Hearing)

A lawyer and a doctor (both impaired of hearing) were riding a bus in New
York, and here's an excerpt of the conversation they were having:


L: So you mentioned that you sue people all the time?
D: Yes, sewing is part of my job.
L: In that case I can give you my card, I could be useful to you.
D: Sorry we do only livers.
L: But I am alive, dont you think I qualify?
D: But you look fine to me, and I don't see a reason to cut you?
L: Well, I could sue you for saying that. I am kind of sensitive.
D: Where did you learn that, I thought you spend most of your time in
court?
L: That's what they teach us to do in court.
D: So do you have a nurse to assist you?
L: Actually the nerds taught us a lot back in school.
D: I think I really learned something today. My station has arrived, I will
see you again.
L: Perhaps we should switch our jobs, from what I learned today.
D: Didn't I tell you before that we stitch only livers.
L: Do you mean I am dead? Look I am really losing my patience.
D: You are deaf too, well I think then we are friends.
