This show started as a one off episode of another Looney Tunes related cartoon. All you really need to know about the theme tune for this one is as follows: Daffy Duck. The 24th (and a half) Century. Tom Jones (and The Flaming Lips). In all honesty, I could just leave it there for this one. But I won't. This is one of those theme tunes that are as fun to sing as they are to hear. It's really all based around the key joke of Tom Jones over-the-top singing the show's title. His voice does make the theme much more epics, even before you put a face to the voice. It's a suitably epic and funny theme tune, and it's a joy to listen to.
