And if that cat item didn't rivet you to your breakfast nooks this morning, TV Column fans . . . let's move to that weird report from NBC that Drew Barrymore . . . the 7-year-old star of "E.T." . . . will be staying up way past her bedtime Nov. 20 to host "Saturday Night Live." (You've got to admit that at least the cat item was kind of wholesome. Phone home, NBC!) . . .
