Unfunniest comedy manga/hwa/huas you've read?

Which comedy manga/hwa/hua that you've read do you consider to be actually unfunny?

It could also be an anime, or a movie, or a TV show or anything really, and it can be any genre (ie. horror, sci-fi, BL, etc.) as long as it's also a comedy. By that I mean, for example, "a romantic-comedy that is not funny at all," and not "a romance that has one joke in the entire story that is not funny."

Trying to see if I have the humour of a 5-year old or if I also think they're not funny. Also if anyone's wondering, for me SPY × FAMILY is literally one of the unfunniest "comedies" I've ever seen. What exactly do people find humorous in it?
