20 Good Years premiered on NBC on October 11, 2006. John Mason and Jeffrey Pyne are an odd pair to be buddies. They're polar opposites in every way and have a hard time seeing eye to eye. The one thing they can agree on is that they only have twenty good years left to live. In their moment of enlightenment, both men vow to live each day as if it is their last, despite what anyone thinks. It's age meets anarchy and there will be no regrets.
