What’s the Tumble Joke-Ha-Thon?

On May 28th at 6 pm ET/ 5 pm CT/ 3 pm PST on YouTube, we'll be hosting a LIVE Joke Tournament featuring some of our favorite podcasters, YouTubers, and TikTokers. Come celebrate kids podcasting and support our work!

Why a Joke-Ha-Thon? To fund the future of kids’ science audio.

Tumble is launching our first-ever Joke-Ha-Thon Tournament Fundraiser — a battle of groan-worthy, giggle-inducing dad jokes. It’s all in support of our mission to make science fun and accessible for kids everywhere.

This isn't just about laughs (though there will be plenty). We’re raising $40,000 to support:

New episodes of Tumble Science Podcast for Kids for Season 11!
Reaching more families, classrooms, and curious young minds with stories of science discovery

Your tax-deductible donation helps keep our episodes free, fun, and full of discovery — and might just win you a prize if your favorite joke-teller wins!

So… what is a Joke-Ha-Thon Tournament?

Think March Madness meets a comedy club — for kids. We’ve invited 10 amazing contestants, from beloved kids’ podcast hosts to science communicators, to face off in head-to-head joke battles. The rules are simple:

Contestants try to make their opponents laugh with cheesy jokes.
But if they laugh, they lose.
Last one standing wins.

When you sponsor a contestant with a donation, you have a chance that they’ll be playing FOR YOU! (Think Wait, Wait, Don’t Tell Me.) If they win, YOU’LL win awesome prizes.

Your sponsorship helps keep Tumble episodes free, fun, and full of discovery — and ensures the next generation of science storytellers can start with a laugh.
