After being called out by Eminem, legendary producer Rick Rubin performed the ALS Ice Bucket Challenge in an epic way.

The 51-year-old Def Jam founder did his challenge a little different than others. Rubin, who is a devout Buddhist, personally filled his bathtub with ice and submerged himself under the ice water. And then he began to mediate in the cold bath.

Granted, we don't know how long he actually stayed in the bath, but this can't be safe to do for a long period of time because of hypothermia. Miraculously, Rubin rises out of his icy bath with no problems. He then nominates singer Frank Ocean and actors Vincent Gallo and Owen Wilson to do the watery challenge.

While Rubin's challenge was indeed epic, we still have to give props to rapper Tech N9ne, who had six buckets of ice-cold water dumped on his head. After that, he took a dive in a pool of ice water. Now that's pretty extreme.

Nevertheless, both men have taken the ALS Ice Bucket Challenge to new levels of epicness. And it's all for a good cause.
