Stern then asked if a story he'd heard about George from back in the day was true -- that the actor had smashed a chocolate candy bar the network sent after the show reached #1 in the ratings. She confirmed the tale, saying he was ticked off because he knew what kinds of gifts other actors received for hitting similar milestones.

"That caused a lot of problems for me," she added. "I should not have sent that picture. But it's so funny."
