Read that as "My girlfriend is 9 years old." I was going to say, just convince her to be a Chiefs fan the same way you convinced her to like creepy old dudes, but...
Buy the kid some Chiefs gear and take him to a game. A lot of kids that age never get to experience something like that...I know I didn't. Not only will he love you, but Arrowhead will instantly turn just about any kid into a Chiefs fan for life.
