The funnyman was the host for the season finale of the show and in his opening skit he compared paedophilia to his love of a popular candy bar.

He said, "Child molesters are very tenacious people. They love molesting children. It's crazy. It's like their favorite thing! It's so crazy, because when you consider the risk in being a child molester, speaking not only of the damage to the child you're doing, the risk, there is no worse life available to a human than being a caught child molester. And yet they still do it, which you can only really surmise that it must be really good. From their point of view! Not ours! From their point of view, it must be amazing for them to risk so much..."

He continued, "If somebody said to me if you eat another Mounds bar, you'll go to jail and everybody will hate you, I would stop eating them. Because they do taste delicious but they don't taste as good as a young boy does... To child molesters. Not to me. Not to us. Because we're all awesome."

He went on to compare the Israel-Palestine conflict to fights between his two children, and joked he was "mildly racist" because of his upbringing in the 1970s.

Following the monologue, many viewers took to social media sites to blast the comedian.

One wrote, "Louis CK Pedophile Sketch is just disgusting SNL40Finale", while another added, "What the hell? Move on from the pedophile jokes Louis SNL."
