How and when did you become fan of your club ?

Only started watching football when i was like 10-11 yrs old.At the time,it was barely my favorite sport as Cricket took precedence,then.
Its only since the 2002 World Cup that i started following football watching EPL games sporadically ,still barely a regular as i was in school and i couldnt stay up at night to watch games.Italy was my favorite team during the WC because of their striking blue color jerseys(as stupid as it sounds) and i was attracted to Del Piero because of his hairtstyle( no homo).
When i was young,i knew nothing of club culture as i come from a non-footballing country and usually i was rooting against teams which i hated the most.For example,Real Madrid was the best team in 2003.They were coming fresh off a Ronaldo  hattrick into the semi-finals and thats where Juventus got my attention as i gave them 0% chance to progress.I watched the repeat ofcourse but there was something about the Delle Alpi,dem whistles and dat atmosphere that really moved me while watching the game,i mean it was unlike EPL atmospheres.Thats where my first connections with Juventus started.
Second connections with Juventus was when i started playing FIFA 04 DEMO(where it had only Milan and Juventus as the two teams) and subsequently FIFA 05 where Juventus were bloody stacked and i loved that team.This is also one the reasons which got me obsessed into football.But between 04-06 again i couldnt watch games regularly because of school.
Then came 2006 WC(where Buffon was by far my fav player) and Calciopoli(which i knew nothing about) and during the 06-07 season,i got to know Juventus got relegated and an air of sympathy grew towards the club from my side.That season on a channel called Zee Sports i used to watch Serie A highlights show where they even used to air Juventus Serie B match highlights.I used to follow it regularly.
At this point,you could still call me a casual Juventus fan until i got internet access that yr and discovered goal.com website in mid 2007.From then on,i never looked back.I educated myself a lot more about the grand history of the club,the great players that donned the jersey in the past and this is when i felt i need to 'support' a club and that was Juventus.Fan interaction on goal.com comments also kinda helped me into becoming a more religious follower and a passionate supporter of Juventus.  
Very frank and honest version of myself here.

Became a Bayern fan at around 7 years old, when I had become aware of football and started playing in a local club, late 80s.

Bayern probably because of my cousin, brother, and local exposure (parents NOT Bayern fans lol), and because I found the names Alan McInally and Radmilo Mihailovic funny to memorize.
For some reason I remember those names best, too, though the player I can remember most from back then was Augenthaler.

Jupp was coach at that time , although that didn't mean anything to me then as far as I remember.
Obviously I didn't really watch games either, only Sportschau (MOTD). Went with my club to Munich to watch some scrub league game against Bochum (5:1 I think) in the Olympiastadium, that was the first time I saw Bayern live.

World Cup 90 was the first major football event I perceived in some detail.

Had a brief flirt with Aleksandar Ristic's Fortuna Düsseldorf a little later as far as I remember, due to some pre-puberty hipster affection I assume.

Then for a couple of years music, pot, skateboarding and generally acting cool in the presence of girls took precedence over being a football fan (not cool), but I started to return in order to worship the GOAT Mario Basler in a Bayern shirt, in time for Trappatoni and his legendary rant, only then to be sucker punched by Solskjär, which event probably ulimately imprinted the depth of my body's emotional capacity for football so that I remained consistently involved since then, though being observant of other leagues or even games than Bayerns has only grown last 10 years or so.
