Have you heard of the “Ice Bucket Challenge”?   It’s a cool new fundraiser for ALS (Lou Gerhig’s Disease) that is sweeping the nation.   Here’s how it works.   Once you’re nominated you have 24 hours to raise a set amount of money for the ALS Foundation, typically $100.   If you don’t, then you get a bucket of ice water dumped on your head.

Recently Justin Timberlake was nominated by the Boston Marathon bombing survivors and he accepted the challenge.   He also issued his own challenge to Jimmy Fallon and “The Tonight Show” crew.   This video proves that Justin is really (and literally) cool!
