re: Nimrods.......
Bugs Bunny, when referring to Elmer Fudd, would say, "What a little Nimrod.." Elmer was of course out hunting down Bugs and the true reference was sarcastic in that Elmer thought of himself as a great hunter (mythical Nimrod) which he was not. To most people it sounded like Bugs was calling him by a word that meant something like idiot.
