Shin Lim blows minds yet again with his "In the Mouth Switch" trick, performed alongside Brooklyn Nine-Nine star Melissa Fumero. In this unforgettable routine, Shin has Melissa sign a card, which she then bites and holds. Meanwhile, Shin holds a different card in his mouth. With a simple touch the cards impossibly switch places—Melissa is left holding Shin’s card, while he now holds hers.
