During this only occasion where Mel Blanc ever actually worked with Peter Lorre, it is unknown whether it entered their conversation about the times in Looney Tunes cartoons that a representation of Lorre interacted on screen with Bugs Bunny as voiced by Blanc in Hair-Raising Hare (1946) and Racketeer Rabbit (1946), or with Blanc's Daffy Duck in Birth of a Notion (1947). "Racketeer Rabbit" had also featured a representation of Edward G. Robinson, who never worked with Lorre on screen in real life.
