What NBC sitcom once saw two of its characters try to pitch NBC on a sitcom about nothing?

The answer is Seinfeld because it is a well-known NBC sitcom where two of its main characters, Jerry Seinfeld and George Costanza, try to pitch NBC on a sitcom about nothing. This iconic episode, appropriately titled "The Pitch," humorously depicts Jerry and George's attempt to showcase their idea for a show that focuses on the daily lives of four single friends living in New York City, with no particular plot or storyline. Seinfeld's meta-commentary on TV sitcoms and its self-referential humor have made it one of the most beloved and influential sitcoms in television history.
