Oprah Winfrey just got her best friend Gayle to pour a bucket of icy water on her head.

It’s some kind of weird celebrity thing, where famous people pour ice water on their heads, scream, and then nominate other famous people to do the same.

(In reality, this is actually for a great cause, people are raising money for the incurable neurodegenerative Lou Gehrig’s disease. If you want to help, you can donate to the Brain Foundation here, or MND Australia here.)

Anyway, here she is, nobly packing ice cubes into a bucket.

And here she is, one of the most powerful humans on the planet, getting drenched by a bucket of ice.

GOOD SCREAM. Solid scream.

And while we’re talking about Oprah, here’s her face over and over a bunch of times.
