Ever since the #ALSIceBucketChallenge began to go viral a couple of weeks ago, we’ve been waiting for it to catch on in Hollywood—and thanks to challenges from Ryan Seacrest, Jimmy Fallon, and more, it did!

In case you’re unfamiliar with the movement, it all began when Pete Frates, a 29-year-old former Boston College baseball player, challenged both friends and celebrities to pour a bucket of ice their heads to help raise money for the disease from which he’s been suffering from since 2012. The rest is viral history. Since picking up speed, the challenge has raised $13.3 million in donations since July 29, up significantly from last year during the same period.

This weekend, many celebrities participated in the challenge to raise money for the debilitative disease more commonly known as Lou Gehrig’s, and the Instagram videos they posted are priceless. From Taylor Swift and Jaime King to Lena Dunham, Oprah, and Kerry Washington, scroll down to watch eight videos of celebrities getting iced for a great cause.

1. Taylor Swift and Jaime King not only accepted the challenge from King’s husband Kyle Newman, Ingrid Michaelson, and Lily Aldrige, they also gathered a large group to participate, too! For everyone in the video, they donated $100 each.

2. Accepting the challenge from Tyler Perry, Ben Affleck recruited his wife Jennifer Garner to dump the bucket over his head. In retaliation, he pulled her into the pool!
