25 Years of Laugh-Out-Loud Moments

Over the years, there's one Oprah Show guest who has never failed to entertain. Actress Kirstie Alley first appeared on the show in her pajamas, and since then, we've seen her in her bra, cleaning toilets and braving it all in a bikini.

Now, Kirstie's taking her moves to the dance floor. She and her dance partner, Maksim “Maks” Chmerkovskiy, are getting rave reviews on ABC's hit reality show, Dancing with the Stars.
