The summer has taken a decidedly chilly turn since celebs began accepting the Ice Bucket Challenge – you know, the social media-driven stunt that's been dominating your newsfeed this month in an effort to raise awareness and money for Lou Gehrig's disease. (Participants must decide within 24 hours whether they want to dump arctic H2O on their heads or donate $100 to the ALS Association in the most common variation of the challenge.)
Cold water, bikinis, a good cause: Really, it's no surprise stars from Katie Holmes and Neil Patrick Harris (the latest to feel the freeze) to Taylor Swift and Justin Timberlake have reached for their respective buckets, put on their bravest faces and accepted their cold, cold fates.
Frankly, we're still waiting, ice cubes ready, for celebs to extend the challenge our way. Until then, we've rounded up the best of the best bucket-dumpers, which is a fancy way to say we're showing you the videos with the most skin and loudest screams.
