Melissa McCarthy and James Corden trying to talk with a mouthguard is super scary

Melissa McCarthy is one funny lady!
The hilarious woman stopped by The Late Late Show With James Corden to promote her newest film and James ended up making her wear a mouth guard.
The teeth make us feel a wee bit uncomfortable but it's funny to say the least!
Watching her vigorously try to blow bubbles, had us in fits.
