Bugs Bunny might've thought he was done dealing with Martians. Not so fast.
In 1952's "The Hasty Hare", Commander X-2 (more commonly known as Marvin the Martian) is sent to Earth to retrieve a specimen. Guess who he encounters first??
The script gave Mel Blanc (as Bugs) an excuse to use a variation on a Jack Benny Program gag. I'm sure you know which one.
