I grew up on Looney Tunes, and sometimes I've scared my husband by knowing what particular cartoon it is just by the music. No, seriously. :-)
::shrug:: I'm a whack job, so what else is new? ;-)
Anyhoo, this is one of my faves in the Daffy/Bugs/Elmer series of cartoons done by Chuck Jones. (He did all the Road Runner cartoons until the late 60s, when he'd moved on to doing Tom & Jerry cartoons.) And, yes, Daffy actually does say, "Hmm...pronoun trouble!" in this part of the clip.
And gets the smell of cordite in his feathers for being anal about English (reminds me of me - minus the cordite, of course ;-)).
Fun, fun, fun!
