“Saturday Night Live” has been a comedy institution since 1975. The late-night sketch show has some moments that it would probably rather you didn’t remember, many of which were humorously discussed during the “SNL 50” anniversary party.

Jimmy Fallon wears blackface as Chris Rock.

In the summer of 2020, during the Black Lives Matter protests following George Floyd’s murder, many TV networks and streaming services removed episodes in which white actors wore blackface.

The sketch had Fallon pretending to be Rock and talking about crack cocaine. This made social media go crazy, so Fallon apologized on X (formerly Twitter): “In 2000, while I was on SNL, I made a really bad decision. I dressed up as Chris Rock, but I used blackface. There is no excuse for this. I am very sorry for making this decision that I know was wrong, and thank you all for making me face the consequences.”

A Tiger Woods sketch makes light of domestic violence.

In 2009, after Tiger Woods’ mistress was revealed, his wife, Elin Nordegren, was said to have attacked him. “SNL” decided to make fun of the situation. Nothing is funny about this situation, but it is even more awkward when a smiling Nordegren (played by guest host Blake Lively) stands next to a badly injured Woods (Kenan Thompson). Woods has an arm sling on and bandages on his face.

The joke might seem to be about an angry wife getting revenge on her husband for cheating on her. But it also makes fun of real people who suffer from domestic violence.

It’s time to hunt communists!

The worst “Saturday Night Live” sketch might be the 1980s “Commie Hunting Season” with Malcolm McDowell as host. The sketch is about a group of rednecks who want to shoot and kill communists at a demonstration. This is already risky territory, but then Uncle Lester (Charles Rocket) says this in response to how to kill commies if a demonstration isn’t happening: “All you have to do is shoot a Jew or a Black person — there’s a higher chance of you shooting a communist anyway.”

The Claudine Longet Invitational.

Claudine Longet was a petite celebrity in the 1970s. She became much more famous when she was arrested and charged with the murder of her husband, Vladimir Sabich, who was a professional skier.

The 1976 “The Claudine Longet Invitational” shows men skiing down slopes. Suddenly, there is gunfire, and they fall into the snow. Chevy Chase and Jane Curtin comment on what is happening. At that point, Longet’s case hadn’t even gone to trial. So, her lawyers spoke to “SNL” about the sketch. The show said sorry in the next episode.

Sinead O’Connor ripped up an image of Pope John Paul II.

O’Connor sang a song called “War” by Bob Marley. At the song’s end, he showed a photo of Pope John Paul II, tore it up, and said, “Fight the real enemy.” People were outraged, and O’Connor’s career was never the same. In the next episode, Joe Pesci was the host. He said that if he had been there the week before, he would have hit her.
