I've been following forest for 16 years now. The reason is kind of weird but meh...
My father's friend had a Forest jersey and he gave it to me before the war. During the war, I had two videocassettes that I kept watching because I had no more toys or anything, those were the two things that I grabbed when we were leaving, one was Police Academy, the other one was Robin Hood (that cartoon where Robin was a fox). Nottingham kind of grew on me and I remembered that jersey I had before the war and asked my father about Nottingham Forest. He liked them so he knew quite a lot about them and I kept asking him about it, so at the end of the war, I started following them.
They kind of grew on me over the years... And as I like underdogs, I like Forest.
I like Liverpool more, but Forest are battling for the play-offs these days so...
And yes, they show Championship matches here.
