Sad Clown is the complete opposite of what a Clown should be, he does not hold any happiness to him and instead of cheering your day with doggy balloons he will instead sigh sadly and play out auto depreciative jokes, as if he had been hurt enough not to find fun or joy in life anymore. He always looked down and not even the best jokes would make him smile. He was just built that way, the horror of the circus would always be a Sad Clown.
