You know you've achieved true viral fame when you're big in Westeros.

If you want to see Cersei Lannister throw a bucket of ice water over her head in support of ALS awareness -- who knew she had a charitable side, right? -- or Jon Snow or even George R.R. Martin himself, watch the stars and creator of 'Game of Thrones' perform the ALS Ice Bucket Challenge.

Martin and 'Game of Thrones' stars Emilia Clarke (Daenerys), Kit Harington (Jon Snow), Lena Headey (Cersei Lannister), Nikolaj Coster-Waldau (Jaime Lannister), Maisie Williams (Arya Stark), Sophie Turner (Sansa Stark), Pedro Pascal (Oberyn Martell) and Joe Dempsie (Gendry) have all accepted the ALS Ice Bucket Challenge, which seeks to raise money in support of The ALS Association and spread awareness of ALS. Since its conception, this campaign has gone viral, with all manner of celebrity folk participating, from Robert Downey Jr. and his fellow Marvel movie stars to the cast of 'Star Wars: Episode 7.' Despite all those involved, however, there's nothing like seeing Lannisters and Starks side by side in support of such a great cause.

As you watch the 'Game of Thrones' stars accept the ALS Ice Bucket Challenge in the videos above and below, know that it's all having an effect. As of Monday, August 25, the stunt has raised $79.7 million in donations for The ALS Association, which funds ALS research and clinical management projects.

HBO's hit series won't return for some time, but hopefully this will put a smile on your face for now. We'll update you as more videos become available.
