As Betty White’s millions of fans continue to mourn her passing at the age of 99, a new social media challenge has emerged. Thankfully, this one does not involve Tide pods or milk crates. It’s a way to support a cause that was near and dear to Betty’s heart: animals.

For many years, Betty White devoted her time and resources to helping animals and even wrote two books about it. According to CNET, “The Betty White Challenge” invites fans of the late actress to “make her 100th birthday the movement she deserves.” All you have to do is pick a local animal shelter and donate $5 on January 17th, Betty’s birthday. Easy enough.

A Wisconsin brewery is taking on the challenge in its own way. ABC Chicago reports the Commerce Street Brewery in Mineral Point, where Betty’s third husband Allen Ludden grew up and is buried, has had ‘Blonde Betty’ on tap for years. It was a tradition for customers to buy the late actress a beer so that if she ever visited, there would be free drinks waiting for her. The brewery is letting customers keep up the tradition through January and will donate the proceeds to an animal charity.
