I so love this joke.
In a murder trial, the defense attorney was cross-examining the coroner:
Attorney: Before you signed the death certificate, had you taken the pulse?
Attorney: Did you listen to the heart?
Attorney: Did you check for breathing?
Attorney: So, when you signed the death certificate, you weren’t sure the man was dead, were you?
Coroner: Well, let me put it this way: The man’s brain was sitting in a jar on my desk. But I guess it’s possible he could be out there practicing law somewhere.
