Here's Mario Biancci from "Little Man, Ten Feet Tall," played by Michael Davis. Mario and his father Nick (played by Ross Martin) came to the Ponderosa so Mario could play the guitar for Ben's birthday party and Nick could cook the food for the party (Hop Sing happened to be gone). Mario was a talented guitar player, but he admired Hoss so much that he started saying he was going to be a rancher instead!
