In "Extra Large Medium", the two were venturing in the woods when Bruce hears who turn out to be Stewie and Chris Griffin, declared missing at the time, screaming. When Bruce does discover them, he tells Jeffrey that he did indeed find them.
In Something, Something, Something, Dark Side, he is a friend of Admiral Piett, played by Bruce. Piett calls him when he is told that the Rebel Alliance stole Zeus, a dog belonging to a mutual friend named Alan.
He is also heard in "FOX-y Lady".
An unnamed character believed to be Jeffrey was finally seen in the uncensored cut of "Friends of Peter G" in the Quahog Cinema before Peter goes on a drunken rampage. Bruce asks he has time to go to the bathroom and takes offense when Jeffery asks if he has his stub in his pocket.
