If you’ve ever wondered what function your lips really serve, you won’t have to wonder anymore. James Corden got silly with guests Melissa McCarthy and Kristen Schaal Wednesday night using mouthguards that pull your lips away from your teeth, normally used in whitening and other dental procedures. Listen to them try to talk about Trump and Isis, without any lips.
The idea for mouthguard talk came from McCarthy’s new movie, The Boss, in theaters now, and Corden decided to take a few out for a trial run. Apparently talking with your lips spread out from your face wasn’t absurd enough, cause Corden broke out the bubbles. Watch the clip below.
