From A Connecticut Yankee in King Arthur's Court

You see, he was going for the Holy Grail. The boys all took a flier at the Holy Grail now and then. It was a several years' cruise. They always put in the long absence snooping around, in the most conscientious way, though none of them had any idea where the Holy Grail really was, and I don't think any of them actually expected to find it, or would have known what to do with it if he had run across it.
