You've seen all the Ice Bucket Challenge videos by now. Everyone from A-list celebs to your Uncle Arnold's best friend on Facebook has posted videos of them being doused by a giant bucket of ice water. Or by just a water bottle, if they are a huge, huge wimp.
What's the point of all this? It's a fundraising campaign for ALS research (also known as Lou Gehrig's Disease), and basically once you get "challenged," you either have to donate to the ALS Association within 24 hours or get ice water thrown on you. And then you have to challenge other people (usually three) to do the same, and so on and so forth.
