Mr. T
He gave up almost all his gold, one of his identifying marks, after helping with the cleanup after Hurricane Katrina in 2005. He said, "As a Christian, when I saw other people lose their lives and lose their land and property...I felt that it would be a sin before God for me to continue wearing my gold. I felt it would be insensitive and disrespectful to the people who lost everything, so I stopped wearing my gold."
