David Blaine called on one very famous assistant to help with his latest act. Pharrell had the odd task of shocking the illusionist by playing the keyboard during his latest stunt “Electrified: One Million Volts Always On.” With each stroke of the key, one million volts of electricity were zapped into Blaine’s body.

The daredevil spent three days and nights standing in the middle of the electric currents with only a chainmail bodysuit protecting him.

“Now here’s something I never thought I could make a keyboard do…” tweeted The Neptunes producer.
