6. Uncle Leo
Best-known episode: "The Bookstore"
Braggart, book thief, general kvetch — Len Lesser was so gifted at playing Uncle Leo, you could almost feel his vice-like grip on your arm and hot breath on your neck as he leaned in to tell you about Cousin Jeffrey's latest success down at the Parks Department. Leo slunk around stealing from Brentano's ("I'm an old man. I'm confused! I thought I paid for it. What's my name?"), lifting Jerry's watch out of the trash and accusing cooks of anti-Semitism, but he still managed to be loveable. Sadly, we'll never know what his "crime of passion" was. Jerry!
