I do, I watch the show on Boomerang when I catch, and picked up the DVD set a couple years ago. Wacky Races is a fun show -- it's a shame it doesn't run on kids programming blocks semi-regularly like it used to.
I'd love to see a Mario Kart quality kart racer based on Wacky Races. (There was a game a couple years ago, but it looked mediocre at best)
