After Arkansas coach, Houston Nutt passes away and enters the Pearly Gates, God takes him on a tour. He shows Houston a little 2-bedroom house with a faded Razorback banner hanging on the front porch. "This is your home, Coach. Most people don't get their own house up here," God explains. Houston looks at the house, then turns around and looks at the one sitting on the top of the hill. It's a huge 2-story mansion with white marble columns and little patios under all of the windows. LSU flags line both sides of the sidewalk with a huge purple and gold LSU Tigers banner hanging between the marble columns. "Thanks for the home God, but let me ask you a question. How come I get this little 2-bedroom house with a faded Hog banner and Les Miles gets a mansion with new LSU banners and flags flying all over the place, why is that?" God looks at him seriously for a moment and then replies, "That's not Les Miles' house, that's mine."
I first heard it in 1967 and it was Charlie Mac / Bear Bryant. It probably goes back to Knute Rockne.
