Although Amy Schumer hosted Saturday Night Live this week, we have to give it up for Melissa McCarthy who stole the night with her surprise appearance on the show. The Life of the Party actress stopped by the Weekend Update segment playing host Michael Che's doting stepmom, and her performance is just too good to miss. "When Michael was little, he had very juicy little buns," McCarthy joked. "They're still juicy, but they're different now." The 47-year-old comedian also called out Che's co-host Colin Jost, saying "You also, I'm sure, have juicy buns. I've seen you in bike shorts, and I think you look terrific." Watch her hilarious cameo above.
