UFC Women’s Bantamweight Champion Ronda Rousey released a video today issuing a challenge to Sylvester Stallone, Dwayne “The Rock” Johnson and Gina Carano to participate in the ALS Ice Bucket Challenge.

For those unfamiliar, the ALS Ice Bucket Challenge consists of nominating a person to pour a bucket of icy water over their head within 24 hours and capture it on video or donate $100 to ALS research. Rousey was nominated by UFC President Dana White.
