In the sneak peek clip, McCarthy and SNL star Vanessa Bayer candidly converse inside a salon while getting their nails painted in "Saturday Night" and "Candy Whore" hues.
When the two start talking about their favorite West songs, diehard fan McCarthy channels her inner rapper and starts busting out a few bars to a made-up West jam called "Butterscotch Man," which she says is from his "third or 15th album."
"You, drop a beat, I'll lay it down," McCarthy says, before rapping, "Butterscotch man, tater-tot yam, put it in my ham (ham!), butterscotch man."
As McCarthy puts it, we think she totally "nailed it."
