Jennifer Garner explained the reason behind the video that turned her into a meme on the night of the Oscars.

On Sunday, Jezebel writer Bobby Finger tweeted a video of the actress clapping and then stopping short, a shocked look on her face.

“What realization did Jennifer Garner just come to?” Finger tweeted.

The tweet gained over 30,000 retweets and over 161,000 likes. Twitter users jokingly speculated about what had shaken Garner up.

“‘I have never seen Ben [Affleck] and Batman in the same place at the same time!’” one user tweeted.

“That no 13 year old would ever wish to be 30,” another user replied, referencing Garner’s film “13 Going On 30.”

Garner caught wind of the meme and posted videos of herself narrating the clip to her Instagram story.

“Congrats to ‘Shape of Water’ — maybe I should date a fish,” Garner said in the first video.

“Hey Jimmy Kimmel, what’s in your wallet? Wait — where is my wallet?” Garner said in the second clip.

“Can’t wait to work with Lena Dunham,” Garner said in the last installment of the joke. “Wait. Did I sign a nudity waiver?”

Finger posted a montage of the story to Twitter.

“I can’t believe she memed herself,” Finger wrote in the Twitter thread. “What a treat. That Jennifer Garner’s a good egg.”
