ELI5: How do comic TV shows like South Park and Family Guy get away with parodies referencing current events, with copyrighted material, without getting sued?

There is a concept in US copyright law called "Fair Use."

Fair Use says that there are circumstances and situations where you're allowed to use someone else's copyrighted material without infringing the copyright. For example, research, scholarship, and news reporting are all considered fair use.

Parody and satire are also considered fair use. There are a lot of complicating factors, but that's the ELI5.
