Aaaaaah.... the good ol' original theme from the Teenage Mutant Ninja Turtles cartoon.
Who - havin' been a kid in the late 80s/early 90s - doesn't know this one?
It's a classic! Pure and simple!
While I admit, the cartoon in itself wasn't always the best quality animation-wise, the intro was simply perfect...
This is the best version I could find. Taking into account youtube tends to either delete, mute or prevent those from being embed.
