On the internet, still images or GIFs of the scene has been used as reaction memes and image macros, usually in the context of somebody jokingly owning up to something inappropriate or funnily absurd.
The original movie scene features the characters Ben Kenobi (a.k.a. Obi-Wan), Luke Skywalker and the droid R2D2.
Luke bumps into R2D2 and finds out that the droid is owned by an Obi-Wan Kenobi. When he asks his patron Ben whether he knows the man, he reveals that him and Obi-Wan are in fact the same person.
‘Do you know him?’
‘Well, of course I know him. He’s me’
The first use of the scene as a meme leads back to a Reddit post from 2014.
A GIF version of Obi-Wan from the scene was submitted to a GIF reaction subreddit, with the caption saying “MRW the police are appealing for information about a local flasher.”
It took the meme a few years to spread properly on the web.
In 2017 an image macro interpretation surfaced on Instagram that combined an already existing Palpatine meme with Well, of course I know him. He’s me.
Following that, the meme was also featured in other Reddit threads and on Memecenter as well.
