There is the big story and the small story!

 

 The little one is more funny!  "When I first went to JR, the digicode was AB42. After it was changed, JR used it as an example in a paper, but I can't remember which one. I had pointed out to him after reading this article, and he laughed when he pointed out that I had read his article carefully. For your information, I'm going to tell you a good one that you may not know about JR. One day, when I was leaving the IUT where I had just given a course on B at the invitation of a certain Henri Habrias, I went to have a drink at the bar next door . To give you some perspective, there was no Internet or e-mail yet. On the other hand, there had been the Minitel for some time.

The owner of the bar was demonstrating to some good customers a joke that could be found on the Minitel. It was simply a matter of looking for general practitioners in the commune of Champigné (49). I told this recipe to JR who didn't have a minitel at home. That's why he connected to a Minitel freely accessible in a post office one day when he had shipments to make. His problem is that he found the answer so funny that he didn't know what to do to stop himself from bursting out laughing. In case you don't know the answer, here it is: Doctors ILDEFONSE and MONCEIX". P.S. There is currently a practicing Dr. Ildefonse. He is a gynecologist! For young people, know what the Minitel is!  https://en.wikipedia.org/wiki/Minitel. Thanks Guy Laffitte !
