Canada's Greatest Know-It-All

Sensory Overload (2x4)

Air date: Feb 04, 2013

The 7 remaining Know-It-Alls put their concentration skills to the test as they are forced to think during free fall from 11,000 feet. Then they're thrown into a giant 'think-tank' and are forced to sink or swim. Their only mode of escape? Their brains. In the elimination challenge, it's information overload as the bottom 2 are confronted with an overwhelming wall of sound and light.
