What do you call a fake Irish stone?
A sham-rock!
A sham-rock!
"Sham-rock" splits the word "shamrock" into "sham" (meaning fake or fraud) and "rock" (a stone) — which is literally the answer the setup is asking for. It's a rare joke where the punchline is the correct answer hiding in plain sight: a fake rock is a sham-rock, which is already a real, beloved thing. The setup tricks your brain into searching for a clever answer when the word itself was always the joke.
Pause just a beat after "fake Irish stone" to let the audience's brain start hunting before you drop the answer — the recognition moment lands harder with a small gap.
