I'm pretty sure Jerry did him most of the time BUT if you listen to him at the end when Pepe gets the historical landmark papers you here Statler say "Historical land mark?" and it sounds way different from Jerry's Statler. In fact, it sounded a lot like Richards Statler! Did someone else do that particular line? If so I hope they take over Statler because he finally sounded right for the first time in like 13 years!
