The idea of the show is celebrity guests wear eleabotate masks and croon familer tunes. A panel of judges - Ken Jeong, Jenny McCarthy, Nicole Scherzinger and Robin Thicke - have to figure it out.
After Chong's brief pineapple head performance, McCarthy came closest when she guessed "Cheech" (for Chong's comedy partner Cheech Marin).
Other "reveals" include Margaret Cho (poodle), Terry Bradshaw (deer) and Pittsbugh Steeler Antonio Brown (hippo)
