Recognition Failure

Recognition Failure is the trope when a character fails to recognize a famous person that everyone else knows, played for comic effect. This is a popular stock gag in Sitcoms; typically, a celebrity or Special Guest visits the cast, whereupon The Ditz or the Butt Monkey is wondering why everyone else is going crazy over the newcomer.

Of course, for the gag to work, the identification subject must be someone who everyone in the work should immediately recognize, for whatever reason. This is usually done with a renowned Real Life person, though it's also possible to use a fictional celebrity whose fame has been established in the story.

 * As a Running Gag on Rurouni Kenshin, whenever a politician (often a Historical Domain Character) appears, Yahiko has no idea who they are.

Film

 * In Live Free or Die Hard, John McClane fails spectacularly to pass himself off as a member of the culture. Most notably is when McClane fails to recognize a cutout of Boba Fett and tries to cover it by saying he's only familiar with Star Wars.
 * October Sky: Homer Hickam is a big fan of Wernher von Braun, reading his books on rocketry, and one of his most prized possessions is an autographed photo of him. When he wins the national science fair with his rocketry exhibit, one of the people to congratulate him is von Braun, but Homer doesn't recognize him.
 * In Apollo 13, the grandma character doesn't recognize Neil Armstrong and Buzz Aldrin when they arrive to give support.
 * More than just not recognizing them, after being introduced to them by name she asks, "Are you boys in the space program too?"

Literature

 * In the Discworld novel Moving Pictures, the wizards have mostly avoided the "clicks", so when Holy Wood stars Victor Marachino and Delores DeSyne are given the red-carpet treatment, they're totally perplexed by the whole thing.
 * Also, one clicks fan refers to the Patrician as "some local bigwig" trying to get reflected fame.

Live Action TV

 * In Arrested Development, Lindsay is trying to meet men. She is enticed by a bearded homeless fellow described as having the rugged, unkempt appearance of a movie star. When she finds out he's just homeless, she leaves. However, it turns out that the homeless man is actually Real Life actor Thomas Jane, doing some Method Acting character research for a couple upcoming movies by posing as homeless. When Lindsay finds this out, she is enticed again. Tom Jane is confused that she doesn't know who he is, but seems pleased that she thinks he's gross.
 * There was an episode of Fantasy Island where the (fictional) famous person had the fantasy of being somewhere where nobody knew who she was. She was sent to the wilds of [Africa/South America], where she fell in love with an explorer who didn't know who she was. Subverted though in that it turns out he did know, he just didn't care about her celebrity.
 * In The George Lopez Show, Carmen runs away and becomes one of the rapper Chingy's groupies. George ends up being the only person who doesn't know who that is.
 * In the iCarly episode "iLost My Mind", the main security guard of the mental institution has never heard of the web show iCarly, so he's not impressed when Carly and Freddie try to use the fact they are the stars of it as credentials.
 * This is inverted in one episode of Hello Cheeky, in which Tim, Barry and Denis all confuse fellow cast member John Junkin for Doris Day. Particularly surreal as John is middle-aged, male, and bald.

Theatre

 * In Of Thee I Sing, it's a Running Gag that hardly anyone in Wintergreen's party can recognize Throttlebottom as their vice-presidental candidate, or remember his name for more than a few seconds. Throttlebottom's name is omitted or obscured on most of the campaign banners, and in the election-night newsreel, one picture of him is labeled "An Unidentified Man." He is not invited to Wintergreen's inauguration, and only gets into the White House as a tourist.

Video Games

 * This is a Running Gag in Paper Mario: The Thousand-Year Door; whenever Mario meets a village elder, they're behind the times and don't recognize him (to the annoyance of their younger relatives).
 * Pennington quickly uses his detective skills to deduce that Mario is in fact, Luigi.
 * In Mario & Luigi: Bowser's Inside Story, the heroes can't enter two high-class shops in the Mushroom Mall until they've proved that they're the right sort of clientele... even though most inhabitants of the Mushroom Kingdom recognize Mario on sight.

Western Animation

 * At the end of the Batman the Brave And The Bold episode "Cry Freedom Fighters!", Barack Obama congratulates the heroes on their victory. Plastic Man has no idea who he is.
 * In The Simpsons episode "Homer's Barbershop Quartet", Homer meets George Harrison. At first he appears to recognize him, but then he cries out, "Where did you get that brownie?!" It's not entirely clear whether Homer failed to recognise Harrison or knew exactly who he was but just thought the brownie was more important.
 * He also confuses Stephen Hawking with Larry Flint.
 * In an episode of The New Scooby-Doo Movies guest starring Jonathan Winters as himself, Winters and Mystery INC try to convince a farmer to let them stay the night. This exchange happens:

Anticipating that the other visitors there would request his autograph, he brought along a couple hundred autographed photos of himself to hand out to people. But despite spending all day at the baseball mecca, the Yankee great was recognized by absolutely no one...save for one guy who looked at him and said, "Hey, aren't you--?...Nah, you couldn't be."
 * Jimmy Page was refused entry to a event for Led Zepplin after he shaved his beard earlier that day and nobody recognised him.
