A friend of mine was attending Xavier, and one of his professors was also an old-school Jesuit priest. My friend told me that he this professor started to tell outrageous lies, just so he could stop the class and ask why no one was questioning him. Really, the purpose of that lecture was to set the stage so he could talk about critical thinking and telling truth to power.

There's a Doonesbury about a college-prof character that's something like this. (Except the moral of the story never gets across to the students.)
