Cauliflower Cabby was another Total Television pilot that wasn't made into a series. As with Gene Hattree, Cabby was inserted into the Underdog syndicated package, which is how he finally made it to air.
Arnold Stang narrated and was the voice of Cabby and his alter-ego, "The Champion". Cabby tricked out his hack to effect the change from mild mannered to heroic. I think part of the reason it didn't sell was because unlike the rest of TTV's output, Cauliflower Cabby had an all-human cast, yet was formatted similarly to Underdog. Judge for yourselves, peeps.
Too similar to Underdog, and lacking charisma.
