Caller: Umm... I was going to say that I think it's good.
Host: That's wonderful! Thanks for calling in. Now, lately I've been beset by a plague of locusts. Blahblahblah mememe.
Listener 1: What's this person's deal?
Listener 2: Ah, they're just being radioverdramatic. They're really boring in person.
