Very good! That actually reminds me of a similar story from a very well known sportscaster in my country who specialty was, say, rugby. One night he was on duty when a call came in from someone trying to settle a argument about soccer, something like which team had won the most soccer league titles A or B. He replied that he wasn't an expert but he was pretty sure it was team A. Silence on the line, then the voice came back asking Is that Joe Bloggs?, he replied that it was and then the voice said and what the fuck would you know about it? and hung up.
