Country legend Garth Brooks accepted the ALS Ice Bucket Challenge from ET's own Nancy O'Dell -- and things got messy rather quickly.
"It's an honor to accept your ALS Ice Bucket Challenge," Brooks, guitar in hand, tells O'Dell in the video. "It is very much a wonderful honor of mine to accept it in your beautiful mother Betty's name."
The cause of raising awareness is very close to ET host Nancy O'Dell's heart, as she lost her own mother to the disease. She did her own ALS Ice Bucket Challenge on Friday, where she called out Brooks, Jamie Foxx, the LA Dodgers team and Oprah Winfrey, who also accepted her challenge.
"All right guys," Brooks tells his assistants who look excited to douse him with cold water. "Let's get this this over with. I love you Nancy!"
Then, like the winning coach at a Super Bowl game, Brooks gets two huge, breezing buckets of green and orange Gatorade poured over his head, which is mostly shielded by a cowboy hat.
Brooks makes sure to send out a few challenges of his own before signing off. He decides to "take on the black and gold." The country crooner challenges the Pittsburgh Steelers, the Pittsburgh Pirates and the Pittsburgh Penguins.
"Let's raise some money for ALS," Brooks adds.
