Video: One man's fantastic version of the Tetris theme tune
We make no apologies for the fact that you will now be singing the Tetris theme tune all day
For those of you out there who are old enough to remember the days of playing Tetris on a spinach green screen, this video will bring back some great memories.
YouTube user Smooth McGroove (we suspect that might not be his real name) has put together this fantastic acapella version of the iconic theme music using just his own voice as an instrument.
Yes, we agree his beard is fantastic too, before you ask.
