This is the cartoon where Bugs Bunny keeps tricking Yosemite Sam into going off the high dive into a barrel of water. At one point in the cartoon, Bugs is on the the end of the diving board, on one side of a locked, makeshift door which prevents Yosemite Sam from reaching him. Yosemite Sam pounds on the door and says, “Open this door! Open up, I say!” (or words to that effect). Then, he turns to the viewer and says, “You notice I didn’t say ‘Richard’.”
I’m guessing that last line refers to an old 1940s radio show or movie, but I can’t place it. Does anyone know what it refers to?
