You don't have to be fully aware of what you're doing to participate in the ALS Ice Bucket Challenge. Do it an hour after getting your wisdom teeth out, while you're still high on anesthetic? Still counts, even if you can't remember which good cause you're supporting. Even if you don't have a bucket.
