There's so many jokes in vintage Simpsons episodes that I can't understand how they were even written. They can't have made sense on paper. The writing was amazing but so was the cast and the writers had to have so much faith that putting a stage direction Homer shrugs and grunts would be devastating at the right moment. It can't be understated how big an impact they had. Every show, even non-comedy, has borrowed inflections and phrases from 90s Simpsons.
