Miss Rafferty has a mother, and it’s … Meryl Streep?! The three-time Oscar winner made her first-ever appearance on Saturday Night Live during the 50th anniversary special on Sunday night. She popped up as Colleen Rafferty Sr.

Oscar-winner Jack Nicholson, sporting his signature sunglasses, also made a surprise appearance during the special. His appearance, too, marked his “SNL” debut when he introduced Adam Sandler, who sang an original song about the 50-year history of “SNL.”
