David Spade
didn't do the ALS Ice Bucket Challenge (and donate a whopping $100,000) to be funny or cool, he did it because he lost a family member to the terrible disease.

Spade was at Nobu Wednesday night where he told our photog why it was so important to him. He said he hopes all this fundraising leads to a cure so no one has to go through what he's witnessed first hand.

So far, the challenge has raised an incredible $41.8 million.
