Lol! Just dawned on me: Bugsy Siegel (from my earlier post), and Bugs Bunny (from a more recent one).
The Bugs Bunny character was inspired by the Peter Warne character played by Clack Gable in It Happened One Night. There were many elements in the film which influenced the creation of the cwazy wabbit, including a reference to a fictional "Bugs Dooley", a name most likely referencing Siegel.
