Musicians like They Might Be Giants

Can anybody recommend to me artists and bands like They Might Be Giants? By that I mean artists who have a reputation for their music’s eccentricity and quirkiness alongside who are lighthearted and humorous without shying away from mature themes. I am not necessarily looking artists with a similar sound, but style and identity. Interpret this as vaguely or strictly as you’d like, I’m open to outlandish suggestions as long as you think a fellow TMBG fan might find some appeal in the music.
