Never was a fan of Seinfeld, it was funny but don't know, I didn't like the pacing in many episodes or the setups for the jokes and I'd get bored. But honestly you know this shit would hold pretty well even if it's provocative, you still have shows like It's always sunny in Philadelphia or Southpark who do shit way way worse. The characters in Always sunny are so much worse, they're truly completely garbage human beings. It makes watching scenes out of the whole show context weird though, if you have no idea about how horrible the characters are, you might not find it nearly as funny.
