Dr. Dre accepted Tim Cook’s (who himself was nominated by Phil Schiller) ALS ice bucket challenge. Even though he took him past the 24 hour deadline, the billionaire Beats founder, in turn nominated Eminem, Snoop Dogg, and Kendrick Lamar as its customary.

Celebrities and non-celebs alike take the ice bucket challenge to raise awareness of the ALS Association and its efforts to help people with amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig’s Disease.

Besides dropping a bucket of water on their heads, most are also donating to the association.

What a good cause.
