Suggest me a well-written novel that has a sense of humor that borders on silly.

I've been on a run of really enjoyable books lately that have fit this description, and I'd like to keep it going. Examples of what I'm talking about are A Confederacy of Dunces, Inherent Vice, Catch-22, and The Corrections (it may be a little debatable on how silly this one is, but there are definitely some silly parts).

Thanks in advance – this community has really helped me (finally) start reading for pleasure consistently.
