Question 684:Eccentricity

Sitter(but don't sit on this one):

X has made several expressions of his feelings for Y to the media, most notably the "Z incident" which took place on the _____ Show of May 23, 2005. X "jumped around the set, hopped onto a Z, fell to one knee and repeatedly professed his love for his new girlfriend."The phrase "jumping the Z", fashioned after "jumping the shark", is used to describe someone "going off the deep end" in public in a manner extreme enough to tarnish his or her reputation. It enjoyed a short-lived popularity, being chosen by the editors of the Historical Dictionary of American Slang as the "slang term of the year" in 2005 and by the nonprofit group Global Language Monitor as one of its top phrases for the year.
The "Z incident" was voted #1 of 2005's "Most Surprising Television Moments" on a countdown on E! and was the subject of numerous parodies, including the Scary Movie 4, an episode of South Park and an episode of Family Guy. Entertainment Weekly put it on its end-of-the-decade, "best-of" list, saying, "Lesson learned: Tell, don't show."

Too easy, I guess.Nevertheless, name this very popular and extremely crazy incident.

Answer: X is Tom Cruise, Y is Katie Holmes, Z is couch and the famous Oprah Winfrey incident.
