One woman is from Mulga, Alabama, the other from Clanton, Alabama.
They are both grandmothers of six.
One cheers for Alabama; the other for Auburn.
Like most college football fans in the gridiron-crazed state of Alabama, they're mortal enemies this week, as the No. 1 Crimson Tide prepares to play the No. 15 Tigers in Saturday's Iron Bowl at Bryant-Denny Stadium in Tuscaloosa.
"I've never met Tammy, but she really seems to be a sweet girl," said Phyllis Perkins, who is known as "Phyllis from Mulga" on the "Paul Finebaum Show." "But it's Iron Bowl week, so I don't know about her.
"She can probably hurt me physically because she's younger than me. No, I take that back. If she hits me, her ass is grass."
Among Finebaum's legion of loyal and colorful callers, there's none more famous than Perkins, a two-time cancer survivor, and Tammy Bullard, a loyal Auburn fan, who stepped across enemy lines when she married an Alabama fan last year.
