Well there is the man in all black with sunglasses who believes he is a robot.

There was the DDR scene. (dance dance revolution) the guy tries showing up the main character and the main character comes back against him and does the game on expert like amazingly lol.

I distcinctly remember the main character living at home with his grandma or mother or something of the sort, constantly playing a game he is making, Which the man in black I believe steals.

And also I think there is a scene where they are all getting high and there is a monkey involved.

Thanks
