Here's the performance that Dennis spoke about on air that he could not understand why anyone would find entertaining.

The pop star Sia performed 2 songs off her album "1,000 forms of fear" and Dennis wasn't sure what to make of the performance. Apparently Sia is known for not looking at the crowd while she performs. Even if you get past that, the performance as a whole was just very odd. Check out the footage below and let us know what you think of the SNL performance.
