Phil Hartman was a writer and voice, he was murdered by his wife in 1998, she then killed herself. This trauma impacted the families and friends and is roundly considered the point where what had once been fun and groundbreaking became a job...
Can’t beat the first four to five seasons imo. I watched a recent episode the other day and the writing is just abysmal, like they hired some YouTubers/Streamers or something.
