GOT7's Jackson and BamBam partnered up to perform J.Y. Park's latest single "Who's Your Mama," with Jackson playing the female counterpart to BamBam, who dressed up as a younger version of J.Y. Park. If Jackson's cross-dressing hasn't already got you snorting out whatever you're eating, his dramatic, provocative(?) performance, during which he does a full split in a short skirt, sure will! At the end of the song, Jackson suddenly declared, "Mom, I'm sorry," making the judging panel burst out in laughter.�

G-Friend, EXID, MAMAMOO, Nine Muses, and more also gave performances on the program's Chuseok special preliminaries and the final rounds, so check them out below! The winners who gave the best performances were M.I.B's Kangnam and GOT7's Jackson, who got to take home some delicious, juicy Korean beef.�
