When you are really bored or annoyed, try ‘QWOP’! It’s a game in which you need to control a guy’s thighs and calves to make him run a marathon. It’s pretty difficult so he falls over a lot. You use the keys ‘Q’ ,‘W’ ,‘O’ and ‘P’ to control him and incidentally ‘Qwop!’ is also the sound he makes when he falls on his face.
This is apparently a big hit on the net since there are oodles and oodles of YouTube clips and forums devoted to it. Like this guy, who added great music..
