Nancy Cartwright (Bart Simpson) was supposed to be on this superstar animation voice acting panel that was hosted by Dick Orkin and Dan O’Day, but a last-minute emergency forced her to cancel. As you’ll hear, the live attendees had no idea who "that guy" was Dan & Dick brought in to replace her…until they heard Dan Castellenata speak and realized they were face-to-face with Homer Simpson.
