John Stewart loses most of his funniness

At the moment he's still funny, but things are starting to change.
His cynical behaviour has been noticed by his staff and most Comedy Central Executives. It's like he's losing the will to live and be funny. He's just getting older and changing into Steve Colbert.
Maybe there's still time for him to rekindle the yellow farty light, who knows ..
