I am looking for an idiom that can be used when someone is trying to make fun to alleviate of a unpleasant situation.
Example: Stockholm City has a big construction in its center that clearly affects both locals and tourists and of the way to make fun of this is through nice and funny banners.
My native language has something that translates to "fun of trouble", but I do not know if this sounds OK in English.
Question: Is there an idiom describe makinging fun of an unpleasant situation?
