Imma upvote you for the quote, but YSK it's "risible" which is an additional layer of humour if you're familiar with Latin (which was what the Romans spoke), because "risible" is an archaic English word from around the 1600s meaning "to provoke laughter", which is itself based on the Latin word "ris", which means "laugh". "Ridere" means "to laugh" and "ridiculus" means "laughable".
