Jumped the couch

See also
jump the couch, or jumping the couch

Bizarre behaviour or statement(s) of a formerly beloved celebrity recognized as the exact moment when the world realizes this person has lost touch with reality and their popularity plummets.

Inspired by Tom Cruise's behaviour when he tried unsuccessfully to convince the world of his mutual , non-transactional, hetero love for Katie Holmes.

See also "Jumping the Shark" as the original idiom, which was coined in 1985 by Jon Hein in response to a 1977 episode from the fifth season of the American sitcom Happy Days, in which Fonzie (Henry Winkler) jumps over a shark while on water-skis. The phrase is pejorative and is used to argue that a creative outlet or work appears to be making a misguided attempt at generating new attention or publicity for something that is perceived once to have been widely popular, but is no longer.
