On Jimmy Kimmel's website, Hugh McIntyre of The Hanso Foundation is scheduled as a guest on Wednesday night (tonight). No other information is given, but over at The Hanso Foundation's website is McIntyre's bio. It doesn't include a photo -- only a question mark -- but lists McIntyre as the "public voice of The Hanso Foundation".
