The last two are the best:
ATTORNEY: Now doctor isn’t it true that when a person dies in his sleep, he doesn’t know about it until the next morning?
WITNESS: Did you actually pass the bar exam?
ATTORNEY: Were you present when your picture was taken?
WITNESS: Would you repeat the question?
ATTORNEY: She had three children, right?
ATTORNEY: How many were boys?
ATTORNEY: Were there any girls?
ATTORNEY: How was your first marriage terminated?
WITNESS: By death.
ATTORNEY: And by whose death was it terminated?
ATTORNEY: Can you describe the individual?
WITNESS: He was about medium height and had a beard.
ATTORNEY: Was this a male or a female?
ATTORNEY: Do you recall the time that you examined the body?
WITNESS: The autopsy started around 8:30 p.m.
ATTORNEY: And Mr. Denton was dead at the time?
WITNESS: No, he was sitting on the table wondering why I was doing an autopsy on him!
ATTORNEY: Doctor, before you performed the autopsy, did you check for a pulse?
ATTORNEY: Did you check for blood pressure?
ATTORNEY: Did you check for breathing?
ATTORNEY: So, then it is possible that the patient was alive when you began the autopsy?
ATTORNEY: How can you be so sure, Doctor?
WITNESS: Because his brain was sitting on my desk in a jar.
ATTORNEY: But could the patient have still been alive, nevertheless?
WITNESS: Yes, it is possible that he could have been alive and practicing law.
