We've seen a wide range of ALS Ice Bucket challenges, from basic ice water dumps to Superman himself Henry Cavill getting six buckets of increasing size dumped on him while in costume.  All of that pales in comparison to Akerman and Gugino's challenge.

Originally challenged by their 'Watchmen' director Zack Snyder, Akerman and Gugino took it to the next step by not only doing their challenge together, but kissing while having the water dumped on them.  Just try not to remember that they played mother and daughter in 'Watchmen', unless you're in to weird stuff like that.
