Don't know if there is an "official TF" explanation, but here is my take. At least hamburgers have some nutritional value. Jelly donuts have none. They have no redeeming value - kind of like ol' phatty himself.
I think the reputation of UT has gone down the drain over the past few years. I am from Tennessee and consider them my 2nd favorite team. I find it embarrassing that I think of UT as a bunch of thugs now (that crawl ESPN ran across the bottom of the screen during the LSU game is a perfect example.) I believe that would have gotten Phil the ax in Baton Rouge quicker than his record. Thoughts?
