Bad / Stupid
farce - A deceptive action that someone tries to fool others into believing that he takes it seriously
Everyone in town knew that a bridge at the busy intersection was needed, but they felt that all the Mayor's activity about the subject was just a farce because he didn't really take the problem seriously.
dunce - A derogatory term used to ridicule someone who is not very clever, or who does not learn easily.
Being called the dunce of the class motivated Joe to work harder and he finished top of the class. Now sometimes he puts on a joker's costume to make fun of those who used to make fun of him.
