(S01E14) If you can believe it, this particular episode is perhaps the strangest of the entire series. It arguably is one of the most famous as well, because it is so different from the rest.

When watching it, you might be interested to know that CBS did not air it originally back in the late sixties, apparently due to some anti-war sentiment expressed by the episode. Whether this is actually true or not is open to debate, but just the same, it makes for interesting viewing.
