Wacky Races or Yogi's Space Race?
I prefer Yogi's Space Race even though it is a spin-off. Mainly because I love Sci-Fi and it was one of the first cartoons I ever remember regularly watching next to Voltron which I think was on the same channel at one time?
A shame that it never got an official relase like Wacky Races though.
Try not to take life too seriously, no one gets out alive.
