Shakes the Clown

Shakes the Clown is a movie starring Bobcat Goldthwait, Julie Brown, and Bruce Baum. Shakes is good at his job as party clown - when he's sober and shows up. Five druggy clowns frame him for the murder of his boss.
Shakes plods about his duties as party clown, and uses all of his free time getting seriously drunk. Binky, another clown, wins the spot on a local kiddie show, which depresses Shakes even more, and his boss threatens him with unemployment if he can't get his act under control.
