In the clip, cast favorite Kate McKinnon tries out a new nickname patterned off of the "Blessings" rapper.
"I'm Aziz Ansari, and I'm hosting Saturday Night Live this week with musical guest, Big Sean," Ansari says.
"And me, Medium Kate," McKinnon interjects. "Sometimes petite, depending on the store."
Sean takes it upon himself to inform McKinnon "that's not how it works."
In a second promo, McKinnon promises that even though she might not be ready for the upcoming episode of SNL now, we'll be able to count on her at show time.
"I have a thing," she says. "It involves a specialist and my feet, but I will be ready if all goes according to plan."
SNL airs this Saturday at 11:30 p.m. ET/PT on NBC.
