Kathy Griffin just stepped up to the challenge ... and left her clothes at home!
The comedian is the latest celebrity to accept the ALS Ice Bucket Challenge, debuting her video on "Jimmy Kimmel Live!" on Friday night.
But Griffin's came with a twist.
The 53-year-old was dared to do it absolutely naked by buddy Suze Ormon and Kathy didn't back down -- shooting her video completely in the buff.
She also enlisted some famous friends to dump the ice-filled water over her head, as both AJ McLean from the Backstreet Boys and "Parks and Recreation" star Aubrey Plaza assisted with the production.
Check out the video above.
Griffin is one of many stars who have brought attention to the cause. So far, celebs like Hugh Jackman, Tom Cruise and even a Superman suit-wearing Henry Cavill have made videos as well.
