Classic Johnny quest, a bit. The new adventures of Johnny quest, YES. That was an amazing series! That was one of my favorite action cartoons back when I was a kid besides batman. Batman was #1 in my book for cartoons, it was dark which was something I really liked about it (This series http://www.imdb.com/title/tt0103359/ made by WB).
I believe they still show the Real adventures of Jonny Quest on boomerang, otherwise the only real way to watch that show is through episode uploads on the internet or by buying the DVD of the series.
