Our chairman, Lee DuBridge, with anguish in his voice, spoke up, "You mean they sat on the platform with you?"'

From an Oral History of Caltech:

The play readers group in 1987 decided to renew the play-reading party, which was one of the great traditions of the fifties and early sixties. And Bob Oliver asked me if I\u2019d dust of f A Broader View. Well, I looked at it and I thought of updating it. But the shift in the twenty years had been so much that updating was impossible; it\u2019s just a period piece or nothing. So we had to do it unchanged. And then I felt honor bound to write a sequel to it, which is called Troll\u2019s Progress. The theme of it is that the essential Caltech never changes. It\u2019s firmly founded on terror. [Laughter] And no froufrou can disguise that fact. And people who play together pray together, twitch together, stay together. Anyway, that theme allowed for a number of wisecracks, and I like to think the dialogue is rather funny. The kids who did it were tremendous. The undergraduates, of course, we know are stars.

Bauer is a very productive mathematician who maintains a well-read blog, and it was through that blog that the phrase began to circulate, eventually becoming something of a shibboleth, signaling, perhaps a rather superficial acquaintance with the subtleties of intuitionistic logic.
