Sheen's website is named "Torpedos against Tornados," a spin off from his "My Violent Torpedo of Truth" stage show. The site says donations will be tax-deductible and will go to Alabama victims of the April 27 twisters.
Sheen started the online campaign two days after he visited tornado-ravaged Tuscaloosa. He pledged to organize a benefit for the area, but there's no word if an event is in the works.
