Episodic

One of the most common aspects of sitcoms is the episodic aspect. It's the return to normality no matter how an episode of a television show ends, the new episode will start as everything is normal and previous episodes will not be referenced to that often.

South Park is one of the most well known obscene sitcoms. It's been around for about 14 seasons and is still going strong. The key to being so successful? Being episodic. No matter how an episode ends, the next one starts new and fresh. One main episodic aspect of the show is Kenny, the friend in the orange hoodie who died almost every episode for about 10 seasons straight.

No matter what, Kenny returns every episode. Why? Because it's funny.
Also, being an animated sitcom can do the impossible and redraw everything is normal in the next episode. Mecha Streisand is a great example. Barbara Streisand turns in Mecha Streisand, and destroys the town. But in the next episode, every building is back to normal.
