Epic Lip Sync-Off From Late Night With Jimmy Fallon [VIDEO]
Stephen kicks it off with a rousing number from DJ Jazzy Jeff, 'Boom Shake the Room' and continues the angry dance even after the song is over.
Next Jimmy Fallon takes on Human League's 'Don't You Want Me' - complete with strutting dance moves.
Third JGL takes the mic and starts with the classic, 'Tiny Dancer'. He really rocks it out making full use of the microphone stand.
Jimmy then takes back the night to introduce Stephen Merchant who elects not to use the mic and to perform 'Single Ladies' by Beyonce... and oh yes the famous dance moves are performed.
Jimmy performs the 80's classic by A-Ha 'Take On Me' with jerky dance steps and gets the crowd involved before the final performance by Joseph Gordon-Levitt.
Joseph Gordon-Levitt steps up without the microphone to perform what contemporary pop classic 'Super Bass' by Nicki Minaj. His performance is excellent and cheeky.
Jimmy declared them both winners, but who did you prefer?
