The riff: Asked quizzically by Mike after the title card passes.
The explanation: Toastmasters International is a nonprofit educational organization that operates clubs around the world that focus on teaching public speaking and communication. They operate speech contests, tutorials and do video series on overcoming speech anxiety and the like.
Novelty factor: I’d never heard of the organization before, but I find its name amusing. I guess he added “ancient” because it’s an older, black and white film, but it strikes me as an odd choice of words.
