It has quickly become a viral sensation as celebrities, athletes and others have chosen to let someone dump ice water over them as a way to raise money for research into ALS, also known as Lou Gehrig's disease.
Recently, head athletic trainer Rick Burkholder was challenged to participate in the chilly antics by the Minnesota Vikings athletic training staff.
In response, Burkholder, his staff and general manager John Dorsey accepted the challenge, donated to the ALS Association and passed the challenge onto others.
