Need any proof? Just follow this here linky and scroll down to the "Spurrier has a winning record..." section. He takes a swipe at the Hat.
I still chuckle every time I recall his swipe at Auburn, many years ago. After a library burned on AU's campus, SOS stated "I heard a sad story today. The Auburn library burnt to the ground. The sad thing was all 20 books were completely destroyed. What's worse, 15 of them hadn't even been colored in yet!" Then there was his line "You can spell Citrus without UT."
Now LSU is the victim of his sharp tongue.
