Lawrence "Moe" Curls is a circus clown at Berry Big Circus. 

Moe is a classic example of a man hiding his sadness behind laughter. At first, he seems to be a happy and immature man who constantly makes bad jokes. However, he quickly becomes sad at the mention of his daughter, Larina, who lives with his estranged wife and so he doesn't see her often. He also suddenly becomes serious if the ringmaster or Bat come up in conversation.

Moe takes his job as a clown very seriously. He practices falling down 100 times every night to perfect his breakfall after slipping on a banana peel and his desk is crammed full of joke and clown books, which he claims to spend every free moment studying or reading
