Mabrah
A complete idiot who thinks he's the dumbest man alive and laughs at his own nonsense while everyone else is trying to die.
Mabrah: 'I'm the dumbest person ever!' (He just ate a whole cake.)
Mabrah: 'I'm the dumbest guy alive!' (He tried to speak in pig Latin.)
Mabrah: 'I'm the dumbest man on Earth!' (He tried to ride a chair.)
