These Guys Love Charity So Much, They Got Naked For Their Ice Bucket Challenge

Emblem3 goes nude for charity.

Emblem3 -- the boy band that sang "Chloe," minus a member -- are the latest ice-bucketers in the ALS Charity Challenge That Took Over The World And My Facebook Feed (real title: “Strike out ALS Ice Bucket Challenge for Lou Gehrig’s Disease"). The ALS fund-raiser started as a small social project, where friends would dare each other to dump ice-cold water over their heads and donate $10 to the ALS Association. If you refuse, you pay even more money to charity -- $100. But Emblem3 are a little different: they're doing it naked.

The guys shed their clothes and took to Instagram, nominating Oprah Winfrey, Demi Lovato and 5 Seconds of Summer before dumping the icy H2O over their bums.

Of course, this clip was pulled from their Instagram, but it lives forever on YouTube.
