A girl I knew in college was supposed to have read The Stranger. She didn't. And she had a class in just about an hour where she was bound to be called on by the professor to discuss it.
Having read it in high school I gave her a quick, short description of the story, pointing out some of the highlights and themes, so she would have just enough to get by.
But being kind of a jerk, I also told her that if she really wanted to impress her professor she should bring up the "story within the story" about Idi Imin and his quest for the Holy Grail.
For those of you unfamiliar with The Stranger, Idi Imin and a quest for the Holy Grail are found nowhere in the novel. And, fortunately for her, she never had the opportunity to "impress" her professor with her knowledge of this non-existent tale.
We all had a good laugh over it, including her, although she was a little pissed at the time.
So I was glad to hear that this practical joke is still alive and well, having apparently most recently been played on Nancy Pelosi.
Good times. Good times.
