The Captain America Elevator meme is a multi-panel format inspired by the 2019 film Avengers: Endgame. It references a previous scene from Captain America: The Winter Soldier where Steve Rogers fights Hydra agents in a crowded elevator. In the Endgame version, Steve avoids the conflict by whispering 'Hail Hydra' into Agent Sitwell's ear. However, the internet reimagined this scene as a vehicle for dad jokes or unpopular opinions. In the meme format, Steve says something controversial or pun-heavy, leading to the tense standoff exploding into the famous fight sequence. It became a viral sensation in early 2020 as a humorous way to mock cringeworthy puns and socially awkward statements.
