A Twist Ending that used to be guarded carefully as a Spoiler, but thanks to Popcultural Osmosis, everyone within the target demographic knows the ending already, even those who haven't even seen the show. It's probably never going to surprise anyone again. In many cases, the twist becomes the central fact known even to those only noddingly familiar with the work, and other adaptations take it as read from the beginning. Named after a line from Family Guy where Peter records the above quote over the best-known example of this trope, Orson Welles' film Citizen Kane.
