Charlie Sheen Does His Own Version of the Ice Bucket Challenge

Charlie Sheen Ice Bucket Challenge With a BIG Twist (TMZ)

Charlie Sheen didn't douse himself with water in the Ice Bucket Challenge ... but he did make it rain.

Charlie was called out by hockey star Ryan Miller to take the challenge in support of the ALS Foundation. But Charlie's challenge was H20 free ... and way more awesome.

He also calls out Jon Cryer, Ashton Kutcher and nemesis Chuck Lorre to meet his challenge. Watch the video ... he doesn't seem hostile toward them.

So how much money do you think was in the bucket?
