1. "Three Fingers" Yarmy, a deceased pool champion mentioned by The Shark during a game with Maxwell Smart. When told that one of his shots was similar to Yarmy's, Max claims to have stolen it from him "last week". When told that Yarmy was long dead, Max replies, "Good. What he doesn't know won't hurt him". [Episode #18: "The Dead Spy Scrawls".]
2. One of the top-flight defence attorneys whose services the Chief is unable to secure for Max's murder trial, forcing him to rely on the less-than-stellar Hanrahan. [Episode #78: "Don't Look Back".]
The use of the name"Yarmy" for these unseen characters is an in-joke referring to the fact that Yarmy was Don Adams' real last name.
