I've heard Mel Blanc, you're no Mel Blanc.

We've been watching the "Buck Rogers in the 25th Century" series, we've almost worked our way through all the episodes.

For some reason, about 8 of the episodes of the second season didn't have Mel Blanc doing the voice of Twiky. It was kind of annoying. They just slipped him back in after that, and the funny headache I was getting while watching the episodes went away...
