Bill Nye (born as William Sanford Nye), best known as Science Guy, is an American comedian, television host, science educator and mechanical engineer. He was invited to Malcolm Tunney's scientific presentation on Earth and global warming in 2008. When the experiment Tunney was performing got out of hand, Bill Nye helped fix the problem. He also appears to be friends with Neil deGrasse Tyson. (SGA: "Brain Storm")
