All Voices for character actor Leonard Stone (photo above). Most of the obits mention that his most famous role was as Violet's father in Willy Wonka & the Chocolate Factory. Am I the only one who remembers Stone from a series of 70's Alka Seltzer commercials. He and another actor portrayed characters named Conk and Bonk. They wore derby hats and pinstriped suits. One had a large mallet and the other wore boxing gloves. They would give people "the old one-two." I could not find one of these on You Tube. I do know they inspired villains in Spider Man comic books.
