Tiffany Haddish made history as the first black female stand-up comedian to host "Saturday Night Live."
The "Girls Trip" star brought comedy to her opening monologue. She talked about a slew of topics, including watching "SNL" when she was living in a group home as a kid, Donald Trump's hair and the current sexual assault epidemic in Hollywood.
In the monologue, she gave "Tiff's Tips" to the men of Hollywood: "Listen fellas. Listen. If you got your thang-thang out and she got all her clothes on, you're wrong. You're in the wrong."

She added, "Wait 'til she takes her own clothes off and then pull your thing-thing out."
Singer Taylor Swift performed two songs from her newly released album, "Reputation."
Earlier this week, Haddish appeared in a promo with the "Look What You Made Me Do" singer in which the comedy queen asked the pop star if any of the songs on the notorious album were about her.
In another promo for the show from earlier this week, Haddish walks through the studio with "SNL" cast member Aidy Bryant. Haddish spies a big red button on a wall with a sign that heeds the warning: "Do not push."
Bryant tries to tell Haddish not to push the button.
"Lady, there's something you need to know about Tiffany Haddish. She pushes buttons," the comedian says. "Especially ones that she's not allowed to push."
Pushing the button makes the lights dim and ejects "SNL" cast member Kyle Mooney from the studio.
This year's cast features Kenan Thompson, Kate McKinnon, Cecily Strong, Aidy Bryant, Beck Bennett, Kyle Mooney, Colin Jost, Michael Che, Pete Davidson, Leslie Jones, Mikey Day, Alex Moffat, Melissa Villaseor, Heidi Gardner, Luke Null and Chris Redd.
