Some riddles are short, silly, and impossible to forget once you hear the punchline. Today’s question is: What do you call a cow with two legs?
The answer
Lean beef!
That’s the traditional punchline. It plays on two meanings of the word lean. Lean beef means beef with relatively little fat, while something standing on just two legs might be pictured as leaning to one side.
Why this joke makes people smile
Rather than expecting a complicated explanation, the riddle takes a familiar food phrase and gives it a ridiculous new meaning. It works because the question leads you to imagine a funny-looking cow, while the answer uses language from the dinner table.
There is also a related version: “What do you call a cow with no legs?” The familiar answer is “ground beef.” Both jokes follow the same playful pattern.
Give someone a moment to guess before revealing the answer. Did you think of “lean beef,” or did you come up with a different punchline?
