Watch: Taskmaster season finale challenge, the greatest pillow fight of all time

Amy Gledhill, Armando Iannucci, Joanna Page, Joel Dommett, and Kumail Nanjiani take a swing at a fluffy and furious sleepover tradition.

Taskmaster Season 21 is drawing to a close with episode 10. So, what challenge could Greg Davies and (little) Alex Horne have for celebrity contestants? Well, Mashable has an exclusive sneak peek with the clip above, featuring the challengers teaming up to capture on camera "the greatest pillow fight of all time."

Armando Iannucci and Joanna Page make up one team, while Amy Gledhill, Joel Dommett, and Kumail Nanjiani make up the other. With just 20 minutes to prepare, Dommett is not scared but pumped, noting, "This is great! We've got a bona fide action star with us."

Cut to Eternals' star Nanjiani in a cowboy costume, facing off against Dommett in an escalating battle. It begins with a stare-down. Then, some eyebrow wiggling in a close-up known as a "cowboy." Then, they draw — not guns, but pillows. Blood will be spilled, as will teeth, and ... a leg. Meanwhile, Gledhill looks on while cleaning a margarita glass.

What could Iannucci and Page possibly do to compete? Will not having Gledhill get in on the action prove a pivotal error? We'll find out when episode 10 debuts.

Taskmaster airs on Channel 4 in the UK. In the U.S., you can watch Taskmasker on the Taskmaster YouTube Channel.
