Saturday morning cartoons

Ahh, yes. Saturday morning.
In my youth, it was spent in front of the television, watching cartoons and eating from a bowl overflowing with Corn Pops or Quisp (a poor-man's Cap'n Crunch).
The Bugs Bunny/Road Runner Hour opened the morning (before sunrise), while H.R. Puffinstuff ended it (around noon).
In the middle was my favorite, Jonny Quest.
Here's the original opening clip, only in Spanish, with English subtitles.
Gives it a sort of international flavor, mixed with the cool jazz music (my buddy from Dallas, Jim Heath - aka The Rev. Horton Heat - remade the track for the CD "Saturday Morning Cartoon's Greatest Hits").
