Katie Couric (annual salary: $16 million) mentioned in passing this morning her graduation speech at the University of Oklahoma Friday night, but left out the part that the Washington Post reported: that she (or her greed-head speakers-bureau) charged $110,000 for her lame jokes about college alcoholism. (Well, the Post reported the fee, not the speech.) I suppose that expensive personal trainer Katie Couric uses (as Myrna Blyth reported on “Spin Sisters”…at $7,500 a week?) still needs to be paid.Oh yeah, she’s just the girl next door….
