Blanc transitioned into speaking roles, showcasing his talent through a range of sarcastic and eccentric characters. He portrayed various roles, including delivery men with sharp wit and disheveled fight trainers. One notable character was Benny's frustrated French violin instructor, who endured Benny's poor playing before pleading for his payment. Typically, Benny would always be short on cash, needing to make a trip to retrieve more from his vault.

After finally receiving his payment, Professor LeBlanc would exuberantly exclaim, "I'm free! I'm free!" and leave the scene joyfully while singing the Marseillaise. This comedic narrative highlights Blanc's ability to infuse humor and drama into his performances, capturing the audience's attention with his vibrant character portrayals.
