The scene above obviously isn’t from the new Looney Tunes Show on Cartoon Network. It’s actually from a new set of Looney Tunes shorts being created for series of online Phonics lessons: Looney Tunes ClickN READ Phonics.
I can’t vouch for the lessons, but the cartoon segments are surprisingly good (they are actually making ten six-minute cartoons, in which excerpts are spread throughout the lessons). Considering that they are produced in Flash by a handful of people they are remarkable. True, there is no room for Clampett-style exaggerated action here, but they are as faithful as one can be to the originals considering the limitations.
