Attorney vs. Doctor

I read this on my show Friday afternoon and have received so many requests for it, I'm reprinting it here -- but first, I must say that this is probably more than 15 years old. I have no idea where it came from, or whether it actually happened in a courtroom, but it doesn't really matter.

Attorney: "Doctor, before you performed the autopsy, did you check for a pulse?"
Witness: "No."
Attorney: "Did you check for blood pressure?"
Witness: "No."
Attorney: "Did you check for breathing?"
Witness: "No."
Attorney: "So, then it is possible that the patient was alive when you began the autopsy?"
Witness: "No."
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."
