'SNL' Stars Get Roasted by Their Actual Moms in Sweet Mother's Day Cold Open

Kenan Thompson and his mother, Ann, on 'Saturday Night Live' cold open on May 12

The 'Saturday Night Live' cast tried to avoid talking politics in favor of honoring Mother's Day, but their moms made sure to chide them over their frequent Trump sketches.

Saturday Night Live celebrated Mother's Day over the weekend with a number of sketches that paid tribute to the moms of the world -- including a sweet and adorably awkward cold open featuring the castmember's real mothers.

"Now, normally we open the show with a political sketch, which can sometimes be divisive," longtime SNL star Aidy Bryant explained as she kicked off the heartfelt segment alongside her mom, Georganna. "But since tomorrow is Mother's Day, were gonna focus on the one thing we can all celebrate together: moms."

The sketch showed a few universal truths that are sometimes hard for people of any age to really wrap their heads around, which are that our parents won't ever miss a chance to embarrass us on purpose, and their politics are likely very, very different.

Kenan Thompson -- who has been a part of the late-night sketch comedy show for 15 seasons, making him the longest-running cast member in the show's 43-year history -- brought out his mom, Ann, who told her son, "I can't imagine this show without you."

"Like, I actually can't remember when you weren't on it," she quipped. 

And while they tried to avoid politics for this special cold open, some of the castmembers moms couldn't help but chide them over going after President Donald Trump in nearly every episode of the season.

Castmember Mikey Day brought out his mom, Sylvia, and sweetly asked if she "ever thought I'd be on SNL someday."

"No," Sylvia replied, emphatically.

"Oh, awesome," Day replied, trying not to sound hurt. "Well, remember I was in that production of The Crucible?"

"Oh, right," she said. "You know, The Crucible's a lot like this witch hunt against President Trump."

"OK, I don't love that. Let's go!" Day said, quickly ushering his mom off the stage.

Newest featured player Luke Null's mom also had some advice, telling her son, "Enough with the Trump jokes… and why doesn't SNL ever go after crooked Hillary?"

"Mom, I am so new here! Please do not do this to me!" Null yelled, nervously.

Fellow first-season featured player Chris Redd echoed Null's remarks, telling his mom, "Yeah, mom, I'm also new and black, so be cool, please."

"I don't understand why everyone focuses on Trump at all," the comic's mom shared. "You should be focused on Jesus."

"OK, well, Jesus isn't president mom," Redd explained.

"And that's the problem," she shot back, before he escorted her off the stage.

The adorable segment comes to end with all the cast members and their moms standing on the iconic Studio 8H stage as they joined in on the iconic simultaneous delivery of "live from New York it's Saturday Night!"

Following the show, the cast members were joined by their moms at a wild SNL afterparty at Zuma, a high-end Japanese restaurant in New York City. A source exclusively gave ET details about the party, which featured special guests Ariana Grande -- who previously hosted in 2016.

Amy Schumer -- who hosted the show for the second time on Saturday -- also came out with her new husband, Chris Fischer. The cast, their moms, and the host all partied alongside the night's musical guest, Kacey Musgraves.

Other notable after-party guest included Questlove, Justine Hartley from This Is Us, and former SNL castmember -- and Schumer's Trainwreck co-star -- Vanessa Bayer.

As for Saturday's Mother's Day-inspired episode, the cold open was far from the only sketch of the evening that paid tribute to the holiday.

In a great pre-taped sketch,Schumer played a loving mom who got a sweet treat from her kids on the special holiday in the form of breakfast in bed, and she tells her young son that the day his was born was the best day of her life.

"What was it like?" he asks, innocently.

"The day you were born? It was amazing," she said, as the video smash-cuts to Schumer screaming in agony at the top of her lungs in a delivery room in a stark depiction of the actual experience of childbirth, before cutting back to her in bed smiling.

The brilliant sketch keeps juxtaposing the almost-stressfully authentic realism of raising children against the sweet, candy-coated story we tell our kids about the magic of parenthood, before ending with the most honest Mother's Day message imaginable: "To all the moms of the world, thanks for pretending it was easy."

During "Weekend Update," frequent SNL gueststar Melissa McCarthy also made a cameo appearance as Michael Che's step-mom, and she was absolutely adorable.

Rocking an endearing bowl-cut hairdo and a pink sweater that read "World's Proudest Step-Mom," around a baby photo of Che, McCarthy stole the spotlight with a genuinely touching performance that served as the episode's most legitimately heartfelt tributes of Mother's Day.

ET caught up with McCarthy in November 2016, while filming her upcoming comedy Life of the Party, where she opened up about her real-life children -- daughters Vivian, 11, and Georgette, 8 -- whom she shares with husband Ben Falcone.

Check out the video below to hear why her kids often appear in so many of her movies, especially those directed by her hubby.

Saturday Night Live returns next Saturday for its season 43 finale, hosted by Tina Fey, at 11:30 p.m. ET, 8:30 p.m. PT on NBC.
