When we first meet the famously wacky quacker in "What Makes Daffy Duck", he explains to us how hard it is to be a duck during hunting season, the way that one always has to hide from everything. But then, Elmer Fudd and an unidentified fox catch sight of him and proceed to vie for him. Needless to say, Daffy always knows how to outsmart them both.
One might interpret this cartoon as an analogy for the Spanish-American War. Both countries wanted control of Cuba and fought each other over it - they never considered letting Cuba become independent - much like how Elmer and the fox fight over Daffy with no thought as to how he feels.
Of course, I'm the sort of person who reads a little far into stories, so I'm probably seeing something that's not really there. "WMDD" was most likely intended as zany entertainment to get shown before a feature film (and it is really funny). Daffy is his usual far out self - pulling a shower out of mid air, and later doing the same with oil - while Elmer is the eternal sap, as Daffy offers him a contract at Warner Bros (I guess that movie studios never miss a chance to advertise themselves).
Anyway, really good.
