Every Wednesday night a few guys have a meal together. There is a game coupled with the meal: each one of them has to bring an "idiot". The game consists in making the idiots talk about their ideas and passions so that the hosts can have a good laugh.
At the end they will choose the "idiot of the evening". One of the hosts has invited his idiot home so they could go to the dinner together, but unfortunately he gets a severe pain in his back due to an accident that day and can't go to the "meal of idiots". Even worse is the fact that the idiot tries to help him all the time, and naturally does everything wrong and aggravates every situation.
