Daito Manabe, a Tokyo DJ, composer, electronic artist, and programmer, conducted an experiment where he attached electrodes to the faces of four of his friends. The electrodes then sent shocks causing their faces to involuntarily twitch.
The shocks were timed to electronic music and the results are quite amusing.
Also found a little ways down is a video of Daito Manabe performing the experiment on himself.
Check out both videos below.
