The Great Gazoo and Abel used to chill on the same planet, back in the day, and that’s when they made a little bet. The loser was supposed to do some good deeds for the Earthlings, and you know who lost the bet. Anyway, Abel had to stop by from time to time just to check in with the little green dude how everything was going. At least that’s what Abel would tell you if you asked him why he spent so much time chillin in Bedrock. However, the true reason is that he had a secret crush on Betty, and always wanted to get it on with her, but Fred was a good friend and talked him out of it, since Barney couldn’t handle his wife cheating on him.
