Years ago, I heard someone auditioning on the air for a talk show. I remember the potential host's exchange with the show's producer going like this:
HOST: I know many of you are used to hearing (name of regular host, mispronounced) in this time slot.
PRODUCER: (corrects the host's pronunciation)
HOST: Oh, really? Is he the son of (longtime former talk show host on the station)? (Upon finding out he's a former host's son): Well, I'll be darned.
I remember gritting my teeth when I heard that and thinking, "It's a shame he didn't do that research before the show. I'll be shocked if he gets the gig."
Sure enough, management hired someone else.
