Oh, that's some fat brass!
The expression "A sock full of Johnny Quest" is from this comic, specifically a reference to Yoko Kanno's soundtrack for "Cowboy BeBop". I thought it might be fun to share that source material.
And, while we're here, a little segment of a documentary about "Johnny Quest", focusing on the music and the guy who gave it to us. He should have had a career outside of cartoons, you say? But then, how would you know him?
