This cartoon is one of my favorites for a lot of reasons, one of them being that it's a showcase for the sound F/X that were created by Robert Clampett and used throughout in the WB cartoons, even the ones that he didn't direct, such as this one. There is the "bee-whup," the singular "boit," and the most famous one, the "yada-yada-yada." There may even be a couple more I can't think of, but those three are instantly recognizable to long-time Bugs Watchers as Clampett's own.
