Katie Couric bid us adieu last week. The bye-byes to Oprah start today, and culminate Wednesday.

And tonight marks the final appearance of Mary Hart on "Entertainment Tonight."

Hart has been with the show since 1982, and will replaced by a younger blonde, former "Access Hollywood" host Nancy O'Dell.

According to TVSpy, during the final show taped yesterday, Hart's former co-hosts Bob Goen, Rob Weller and NC State grad (and WTVD alum) John Tesh, surprised her.

"ET" and Mary helped turn pop culture and, more pointedly, celebrity culture into mainstream news. (You may not want to thank her for that, but it is what it is.) She's also famous for her gams; her legs were once insured for $1 million each.

In a couple of weeks, we'll be waving to the Today show's Meredith Viera too. Sigh.

Good luck, Mary!
