"A Genuine Court Transcript" joke

Q: Doctor, before you performed the autopsy, did you check for
a pulse?
A: No.
Q: Did you check for blood pressure?
A: No.
Q: Did you check for breathing?
A: No.
Q: So, then it is possible that the patient was alive when you
began the autopsy?
A: No.
Q: How can you be so sure, Doctor?
A: Because his brain was sitting on my desk in a jar.
Q: But could the patient have still been alive nevertheless?
A: Yes, it is possible that he could have been alive and practicing law somewhere.
