"There's one way to find out if a man is honest - ask him. If he says, "Yes," you know he is a crook"
About this Quote
The intent is less about cynicism for its own sake than about puncturing America’s obsession with self-certification. Honesty, in Groucho’s worldview, isn’t a badge you pin on; it’s something you demonstrate under pressure, over time, when it costs you. The crook, by contrast, has every incentive to treat morality as a marketing slogan. That’s why the "Yes" is damning: it’s the sound of someone selling you an identity.
Subtextually, the joke targets the comforting idea that character is easily legible. If all it takes is a question, then we can keep trusting the surface of things - the handshake, the résumé, the confident smile. Groucho’s gag says that surface is exactly where the con lives.
The context matters: Marx came up through vaudeville and the Depression-era entertainment machine, watching hustlers, bosses, and polished public figures thrive on charm. His comedy often treats institutions - romance, money, respectability - as rackets with better lighting. Here, the laugh is a small act of self-defense: be suspicious of anyone who advertises their decency like a product.
