Jerry Seinfeld is remembering his Seinfeld collaborator Jerry Stiller, who died earlier this week at the age of 92, as an unparalleled professional who never required notes on how best to capture the character of Frank Costanza.

"[Stiller] had the most amazing comedic stuff that he—we didn't know if he was planning it or it just came out that way, or he couldn't remember the line, or we didn't know what it was, but we did not want to disturb it in any way," Seinfeld said during a What a Joke with Papa and Fortune interview on SiriusXM Thursday, per the Hollywood Reporter. "We never gave Jerry Stiller a note. I never adjusted his performance once. Whatever he did, that's it. We're putting that out there."
