Over the course of 25 seasons, "The Oprah Winfrey Show" had some seriously memorable moments. There was the time in 1995 when Oprah entered the studio on the back of a 6,000-pound elephant. Another time in 2000 had the talk show host manning the drive-through window at a Chicago McDonald's. And then, in 2004, Oprah and Gayle traded in their modern garb to live like colonials did (au naturel...) 400 years ago.
"I've always said 'The Oprah Show' production team was the best in the business. They're always thinking up some crazy ideas -- mostly for me to do," Oprah says.
On a recent episode of "Oprah: Where Are They Now?" Oprah took a look back at some of the wildest, craziest antics ever performed in "Oprah Show" history.
The video above features some of the show's most out-there incidents viewers can't forget. Watch Oprah repel down a 34-foot wall at Fort Campbell Army Base, see her run through Chicago's West Loop in a pantyhose protest ("This is the dumbest thing I ever saw," she laughed back then), discover what happened Oprah played a prank on an unsuspecting worker at a celebrity look-alike agency and more.
In the video below, "Oprah: Where Are They Now?" Executive Producer Jill Van Lokeren and Producer Julie Mirlicourtois appear on HuffPost Live to talk more about the episode, including the big surprise Oprah got when she worked the drive-thru at McDonald's.
