This is already one of the best charity campaigns ever!
Everyone is getting involved with the ice bucket challenge to support ALS, aka Lou Gehrig's disease, and even Oprah is jumping in on the fun!
The media mogul was nominated by Tyler Perry, and filmed herself filling her own ice bucket (below) before getting dumped on!
And her bestie Gayle did the pouring!
Your move, you three!
