I can slash but I have no knife, I can dash but I have no legs, I can pound but I have no hammer, I can star but I have no stage. What am I?
Common Wrong Answers
“A sword”
A sword is associated with slashing and has a physical form, unlike a keyboard which is an inanimate object that doesn't possess a knife.
“A runner”
While a runner can dash and is associated with speed, they have legs, which contradicts the line about having no legs.
“A drum”
A drum can pound, but it is a physical object that requires a hammer or stick to produce sound, which does not align with the riddle's conditions.
