"The order of eating the meal- first cholent, then kugel and meat- has been passed down through the generations from Har Sinai. Not only is the eating of these three foods a tradition, but so is the order in which they are eaten."
- Rabbi Yosef Yitzchock of Lubavitch (quoted on page 290 of Shabbos Secrets, R. Dovid Meisels)
I don't know if the above quote is accurate or not. However, I have to believe that if it is indeed accurate, it certainly wasn't meant literally. I simply can't imagine that R. Yosef Yitzchock believed that God dictated to Moshe that he should eat cholent first, followed by kugel and then meat at the Shabbos meal. Did they even have the first two in the Wilderness? And how is it that this tradition managed to avoid transcription between the time of Moshe Rabbeinu all the way to R. Yosef Yitzchock's time?
The point, I suppose, is not that R. Yosef Yitzchock made such a statement -- he could very well have made it in an offhand or joking manner. The point, I suppose, is that there are people who take everything any gadol says so seriously as if it were literally and absolutely true that they can't even stop and think for a second if such a thing could even logically be true.
