1. ludicrous, laughable. 2. jocose, jocular, comic, comical. Humorous, witty, facetious, waggish imply something that arises from cleverness or a sense of fun. Humorous implies a genuine sense of fun and the comic, impersonal, or gently personal: a humorous version of an incident; a humorous view of life. Witty implies quickness to perceive the amusing, striking, or unusual and to express it cleverly and entertainingly; it sometimes becomes rather sharp and unkind, particularly in quick repartee of a personal nature: a witty and interesting companion; to be witty at someone else's expense. Facetious suggests a desire or attempt to be jocular or witty but not to be taken seriously: a facetious remark. Waggish suggests the spirit of sly mischief and roguery of the constant joker, with no harm intended: a waggish good humor.
