What was the name of the guide that got sick and couldn't guide Jack O'Connor up Mt. Hujocks for sheeps? I think that was in 1951, but that's not important.
He said that Jack wouldn't use any cartridge that was underrated by the Underrater's Laboratory. This organization is still around and still underrating things - both the ethereal and the earthy.
If you want to get under the skin of any writer, ask about paying your dues to the Underwriter's Laboratory! Hey, we all gotta start somewhere.
