Barracuda
Do you remember "Diver Dan" from the early-to-mid '60s? and the evil Baron Barracuda?
Not quite clearing my synapses just now.
I do. He was on one of the local stations in Sacramento. But I never knew he was syndicated--I always thought it was just a local show.
We also had Captain Sacto, who was a jet pilot and "flew in" every day to host the show, and Cap'n Delta (later renamed Cap'n Mitch when he jumped to a different station), who was a river boat captain. I was on Cap'n Delta's show when I was about 6 or 7, and brought home a load of candy and toys and Wonder bread.
