You had one job is a popular catchphrase, uttered when people want to highlight a poorly executed task of someone else.
On the internet, it is similar to and closely associated with the FAIL image macros.
The line first occurred in the 2001 Ocean’s Eleven, where it is said by Basher Tarr (played by Don Cheadle) who is reprimanding his team for missing an essential step, that leads to the failure of the heist.
An early online case of “you had one job” comes from Reddit user nomdeweb who used the catchphrase with a screenshot of Jurassic Park’s credits, depicting the name of Phil Tippett who was “dinosaur supervisor”.
The post was uploaded to Reddit on April 25th, 2011.
The phrase would become very popular over the years, with a ton of memes containing the phrase “you had one job”.
These include rage comics, as well as image macros on sites like Reddit, Tumblr, Twitter, Facebook and Instagram.
