I, personally, have always been a Chiefs fan.
No one else in my family could give a hoot about football, I just always loved the team.
Sorry I don't have an interesting story to tell about how I became a Chiefs fan, but I can tell you that the first Chiefs game I went to was when I was about 13 or 14.
Since my family are not football fans, I wasn't able to go to a game until our church youth group was allowed to sell programs outside Arrowhead starting about 3 hours before the game.
Let me tell you it was the coldest I have ever been.
After we sold our share of programs we were allowed to get tickets for free concessions in the stadium.
It was freezing cold and the only hot chocolate size they had was a small in a styrofoam cup. Well in my youth, exuberance, and inexperience I requested a large hot chocolate that came in one of those waxed paper cups that soft drinks come in.
Needless to say, I spent all my tickets on the one drink and couldn't drink it because the wax melted and ruined the hot chocolate.
Good times man, good times!
