Bad Luck Blackie (1949, animated short)

Bad Luck Blackie is a 1949 American animated comedy short film produced by Metro-Goldwyn-Mayer.
The Tex Avery-directed short was voted the 15th-best cartoon of all-time in a 1994 poll of 1,000 animation industry professionals, as referenced in the book The 50 Greatest Cartoons.
The title is a play on Boston Blackie, a popular radio show at the time. The cartoon marks the first appearance of Tex Avery's version of Spike the Bulldog (later renamed as Butch the Irish Dog in 1955's Deputy Droopy), who would later appear in Droopy cartoons in the late-1940s into the 1950s.
