How far do you take your sporting passion? Duvet emblazoned with your favorite team's crest?
Replica kit? Every single match attended? Membership of their official supporters club?
Heard about the soccer fan who's passion is costing him a fortune?
Enter Mohamed Henni.
Henni is considered in some quarters as the greatest supporter of Olympique de Marseille.
There is no question or doubt about the fact that this French soccer fan is passionate however this comes at a cost.
There was a time when only premier league rock stars in swish hotels on a world tour were the only people we heard of that smashed tvs.
Ok we've all heard anecdotal evidence of student parties and lad holidays to the canaries where this has apparantly occurred but Henni takes it to a new level.
Henni has gained a reputation for making videos where he gets mad about football players, and then breaks his television with various tools such as baseball bats.
In an age of blogging the Frenchman records himself breaking his own TV whenever his team loses but insists his antics are "to make people happy" and "not for theatre".
It's proving to be a youtube phenomenon as Henni, who has over 1.1 million subscribers, and has probably broken more televisions than Marseille have won games this season.
Golf clubs, a garden rake and his own head have all been used to smash the screen on various occasions.
The sets he's smashing don't come cheap. A quick squint on an online comparison website indicates you'd be lucky to get a tv of any size or quality for less than four or five hundred quid.
Maybe the youtube video video views are generating revenue for him and you would hope they are.
You'd want Harvey Norman dropping sets off your house free of charge on a weekly basis to support your affliction otherwise!
I will stick to roaring from the stands!
