Who was George?

Posted by Q on November 28, 2001 at

As silly as you may think my inquiry may be I would like to ask about a phrase I heard while watching a Bug’s bunny cartoon. In this episode he's playing the piano, pauses to the camera and smirks to say "I wish my brother George were here". Who was "George?
I’m sure when this first aired 50+ years ago-- people got the joke.
It’s amazing to me how much of the humor I didn’t get when I watched it as a child.
(except for this one). Thanks.
