pagliacci
A guy who is always sad, but he makes other people laugh by pretending to be a clown, even though it’s all fake.
My dad is a pagliacci. He laughs at my jokes, but he’s actually crying inside.
At the park, the pagliacci tried to make a kid laugh, but he just cried.
He told a joke, and no one laughed. He just kept telling jokes until he cried.
