This week's upcoming episode of Lip Sync Battle features Rachel Bloom (Crazy Ex-Girlfriend) competing against Michael Shannon (Boardwalk Empire). As much as we love Shannon, it's clear that Bloom — a theater kid — has the obvious advantage here. 

In the sneak peek below, we get a hint of Bloom's performance of Katy Perry's "Teenage Dream." Bloom goes a step further than just lip-syncing and actually channels the awkwardness of being a teenager, right down to the ill-fitting band uniform and the terrible skin. Michael Shannon's going to have to pull out all the stops if he wants to win. 

The full episode airs Thursday at 10 on Spike
