Yucko the Clown
A onetime sad-sack clown who eventually was run out of the circus circuit on a rail because he had such horrifically bad breath that nobody could stomach being around him.
Alas, I once knew Yucko the Clown, he was even voted “Most Pathetic Circus Entertainer of the Year” right before he became a worldwide laughingstock.
