• At the ceremony, which happened on Sunday, Common and Andra Day performed their Oscar-nominated song, "Stand Up for Something," from the "Marshall" movie soundtrack.

Jennifer Garner had one of the most hilarious moments at the 2018 Oscars, which took place on Sunday at the Dolby Theatre in Los Angeles, California.

After Garner was caught pausing mid-clap and seemingly coming to a realization, people on the internet came up with memes that tried to explain what caused the puzzling moment. 

The viral moment happened during the awards show, following Common and Andra Day's moving performance of "Stand Up for Something." The track, which was nominated for best original song, was featured in the 2017 film "Marshall." 

After the performance, the cameras showed audience members giving a standing ovation.

Sally Hawkins, Octavia Spencer, Diane Warren, Steven Spielberg, and Viola Davis were seen clapping, but when the camera showed Garner, memes were born. Garner started clapping, but then abruptly paused and looked like she remembered something or came to a realization. 

The moment of surprise went viral online, and Twitter users were quick to attempt to explain what could have possibly prompted Garner to stop clapping and freeze. 

Many memes were inspired by Garner's position as a spokesperson for Capital One's Venture card.

Other memes referenced her role on the popular ABC TV show titled "Alias."

Some memes were also influenced by Garner and Ben Affleck, who she split with in June 2015.

Additional memes suggested that perhaps Garner came to the realization that she forgot to do something, like unplug a hot appliance or take cold food out of the freezer.

Regardless of what caused Garner's bewildered expression, the moment is relatable.
