Comedian Jack Black encouraged fans to get their COVID-19 vaccination by posting a post-vaccination video of himself transforming into several members of the Avengers.

Posted on Instagram, the clip opens with the School of Rock star standing shirtless and pretending to get a COVID-19 vaccination. The camera then pans to show Black wearing an American Flag Speedo and Captain America helmet as he kicks through a pile of fake bricks.

As the nearly two-minute-long video continues, Black shows off some seriously suggestive dance moves while being hit with spray from a hose. Later in the clip, the Tenacious D musician transforms into other Avengers, including Hulk, Thor, Iron Man and Spider-Man.

The video was edited by creative director Taylor Stephens, according to E! News. Stephens also appears at the start of the clip, as the shirtless body on which Black's head is superimposed. The funny video is set to Jordyn Edmonds' remix of Eminem's "Lose Yourself" and MC Hammer's "Can't Touch This."

In addition to being viewed more than four million times, the video has solicited some hilarious comments from celebrities including Kevin Bacon, Colin Hanks and Thandwie Newton. "Wow. Just wow. Jaaaaaack!!" Bacon wrote, along with fire, red heart and clapping emojis. Meanwhile, Hanks added, "We don't deserve this," and Newton commented, "Jack just got vaccinated. Shit this made my morning. I love this LOVE."

Prior to dropping the video, Black teased fans with snippets of him dressed as the Avengers he portrayed in the final cut. Black's superhero-themed video is the latest in a series of clips he's released as part of his #StayAtHomeDance since the pandemic started in March 2020.

"I am so excited to reunite with Jack, this time in the recording booth," director Eli Roth stated. "Claptrap is the funniest character in the game, and Jack is perfect to bring him to the big screen."
