The police are questioning a witness. The detective asks for a specific detail, such as the date of a past event or the name of a suspect. This is not something a witness would be likely to remember with precision.

However, the witness does remember, exactly and with certainty. Before we can raise an eyebrow, he explains ''why'' he remembers. It turns out he has some connection to the name, date, or other information. The suspect had the same name as the witness's father, or the date was his daughter's birthday.

This is essentially ScotchTape. It saves everyone the trouble of long, boring scenes where witnesses consult their calendars, go through receipts, or any of the other activities one might do in real life to reconstruct such details. On occasion, though, the witness's offhand statement turns out to be a clue, or sets off a EurekaMoment.

Standard in the PoliceProcedural.

[[folder: Film ]]

* In ''SlumdogMillionaire'', the main character is able to answer the gameshow's trivia questions because most of the answers directly relate to memorable events in his life.
* Parodied, like so much else, in ''{{Film/Clue}}''. As he recounts the night's events, Wadsworth suddenly pauses and answers the question that absolutely nobody was asking.
-->'''Wadsworth''': I was in the hall. I know [[CaptainObvious because I was there.]]
* In ''MyCousinVinny'',one of the witnesses testifies that the two Youts., [[spoiler: I'm sorry, the two youths]] took five minutes in the store because he was cooking his breakfast when they went in and eating when the gun shots were heard. Vinny discredits this because he learned earlier it takes twenty minutes to cook grits properly.
* A variant in ''BadBoys'': "Did you hear what I said? I heard what I said, 'cause I was standing there when I said it."

[[folder: Literature ]]

* An inversion in the Isaac Asimov short story ''What's in a Name?'', where the suspect [[spoiler:who works at the science reference library claims they don't remember the name of a furrier named Ernest Beilstein who inquired at the reference desk at the alibi moment. The detective alleges that she could not possibly have forgotten this due to the coincidence of his sharing a name with ''Beilstein's Handbook of Organic Chemistry,'' the canonical sixty-volume encyclopedia of chemical compounds and reactions]].
* In Chrystine Brouillet's French novel, ''Les Neuf Vies d'Edouard'', a witness remembers the exact time he saw a suspect because he was very worried of running late for his plane at the time. This is particularly unnecessary detail repeated as third-hand information to the reader.
* OlderThanTelevision: In the Franchise/SherlockHolmes story "The Retired Colourman" (1926), Watson remembers the number of a theatre ticket because it was his old school number.
* In the novel ''Anastasia Absolutely'', there is an investigation into a bomb found in a mailbox. It's mentioned that one of the letters underneath the bomb was a birthday card, and the police could pinpoint the time it was mailed because the woman who mailed it remembered the song that had come on the radio a moment before.
* In ''Literature/{{Allegiance}}'' a young captured pirate says this phrase, but the stormtroopers who captured him don't care why he remembers which day it had been, so they cut him off.
* An interview with a man who claims to have seen red and green UFOS chasing his car, from Otis G. Firefly's Phantasmagoric Almanac and Calendar: "I remember it real good 'cos it the Fourth of July!"

[[folder: Live Action Television ]]

* Used regularly in the ''Franchise/LawAndOrder'' franchise.
* Can be played for comedy, too. On ''Series/{{Friends}}'', Monica tells Joey that Chandler met a woman named Ginger. "I remember because when he told me, I said "[[Series/GilligansIsland the movie star]]."
** In another episode, Monica remembers precisely what time she ran into Richard despite claiming she's not still in love with him, because she'd been arguing with a clerk over whether or not a movie was late at the time.
* In an episode of ''Series/{{CSI}}'', a man can recall the exact time he heard something suspicious due to having rented a porno pay-per-view movie scheduled to start at that time.
** The same reason is used in an episode of ''Series/VeronicaMars''.
* An episode of ''Series/{{Monk}}'' has a competitive eating champion who tells Stottlemeyer and Disher that an all you can eat buffet he was at at the time of the crime can back him up because: "Oh, they'll remember me."
* In an (in)famous episode of ''ThePractice'' a witness on the stand Remembered Because she was about to go inside to watch ''Series/BostonPublic'' at the time - both produced by David E. Kelley. Infamous because earlier that same season there was a {{Crossover}} between the two shows, despite them being on different {{Networks}}.
* ''HillStreetBlues:'' A court witness with transactional immunity (meaning he couldn't be prosecuted for any crimes related to his testimony) when asked why he was so sure about a date said "because that was the same day I killed a cop."

[[folder: Newspaper Comics ]]

* Parodied in a ''[[ComicStrip/TheFarSide Far Side]]'' cartoon -- a woman points out a man in a police line-up, saying "''That's'' him! ''That's'' the one! I'd remember that dinky little hat ''anywhere!''" The man in question is twice the size of everyone else, with three eyes and a trunk.
