Uncle Leo

Uncle Leo is the brother of Jerry's mother, Helen; his last name is never revealed. In an episode where Leo signs for a package addressed to Jerry, he actually signs it "Uncle Leo". In "The Bookstore", Jerry mentions "Leo" to Kramer. Kramer is initially confused, but upon remembering, he says, "Oh, yeah. Right. Uncle Leo. Forgot his first name."

Uncle Leo is very eccentric and a "general kvetch."[1] When coming across Jerry, he always exclaims his catchphrase, "Jerry! Hello!" with his arms wide open.[2] When Jerry has a Cape Fear-esque nightmare about him in "The Bookstore," Leo has the word "Jerry" tattooed on the fingers of his right hand and "Hello" on the fingers of his left.[3]

When talking to people, Uncle Leo has a tendency to grab the person's arm (often uncomfortably) and hold them close.[4] In "The Pony Remark," Jerry guesses that he does this "because so many people have left in the middle of his conversation."

Uncle Leo often brags about his son (Jerry's cousin Jeffrey, who never appears on the show) and his various accomplishments while working in the Parks Department. Leo is very sensitive about greetings; when Jerry once avoided stopping to talk to his uncle on the street (because Jerry was on his way to a meeting), Leo was offended and called Jerry's mother in Florida to complain about the snub.

Leo is retired. His wife, Stella, is seen in the third-season episode "The Pen", but by the seventh season, he is either widowed or divorced. In "The Shower Head", he is living with a woman named Lydia. He breaks up with her because Jerry joked on The Tonight Show with Jay Leno about Leo's paranoid obsession with antisemitism in ridiculous contexts, such as claiming that a cook is antisemitic for overcooking his hamburger. Lydia found Jerry's comments funny, so Uncle Leo accused her of being an anti-Semite, as well. He resumes the relationship later on in the episode, although neither Stella nor Lydia is mentioned in subsequent episodes.

In "The Package", Leo receives a package for Jerry after Jerry refuses it, being suspicious that it could contain a bomb. Although initially refusing George's suggestion to let Leo open the package, he encourages Leo to open it after Leo asks Jerry to accompany him to Jeffrey's Parks Department production of The Mikado. This happens over the phone, and Jerry hears a loud explosion once Leo agrees to open the box. Except for having his eyebrows and moustache burnt off, Leo is unharmed. Elaine later quickly draws new eyebrows on him with her eyeliner, leaving him with a comical expression of anger.

In "The Bookstore", Jerry catches Uncle Leo in the act of shoplifting at a local bookstore, thereafter, confronting him about it. Leo maintains that seniors have the upper hand since they can claim senility ("Come on! I'm an old man. I'm confused! I thought I paid for it. What’s my name? Will you take me home?"); he also reminds Jerry to always greet him "Hello" no matter how awkward the situation.[3] Jerry later unintentionally gets Leo arrested by "bookstore police" after Leo attempts yet another theft. The episode reveals that Uncle Leo has a criminal record related to a "crime of passion".

"He's the kind of guy who is a total nuisance at times and the kind of guy you avoid. He's a very expansive character, and that has an attraction to it," Lesser said of the character in 1998.[5]

Len Lesser, who portrayed Uncle Leo, exhibited some of the same character traits, especially the overly excited greetings, when he portrayed the character Garvin from 1996 to 2004 on Everybody Loves Raymond.[4]

Lesser died in 2011.[6] His role as Uncle Leo was remembered as an "iconic" and "scene-stealing" character.[7] Despite his persona as a complaining braggart, Uncle Leo "still managed to be loveable".[1]

The Uncle Leo character appears in a total of 15 episodes from 1991 to 1998.
