I also love Johnny Tightlips. What about his counterpart, Frankie The Squealer?
"Okay it's me! I can't help it, I just love squealin'. It makes me feel big!"
Or in TOH XIV, when Homer kills Death and no one can die for a short bit. Fat Tony, Legs and Louie are shooting Frankie:
Fat Tony: "Frankie The Squealer, why won't you die?"
Frankie: "I swear, I'd tell ya if I knew!"
