LISTEN: Mike Francesa, Caller Argue Over ... LBJ?

NEW YORK (WFAN) -- A caller to Mike Francesa's show tried to refer to LeBron James as "LBJ" on Thursday.

Francesa didn't like that.

"To me, LBJ is Lyndon Baines Johnson," the WFAN host said. "LBJ is not LeBron James. ... Nobody calls LeBron 'LBJ.'"

"Different generations," Mike from New Haven, Connecticut, fired back.

"Don't create your own names and expect people to think that somehow they're the norm," Francesa said. "That's not the norm."
