In the late '90s, I heard an aspiring DJ call an AM radio talk show host for advice. He told the host he'd like to work at a classic rock station. The rest of the exchange went like this:
Host: That'll be fine for about three or four years.
Caller: Then what?
Host: Then, you grow up.
That's ironic advice, coming from a host whose recurring slogan was, "I refuse to grow up."
