Need A tutorial on American pastimes.

At work I have to attend lots of formal and informal meetings. I go there but I do not have any kind of discussion with people because I do not share the interests. I have seen grownups talking about video games , which I never indulged into. My eye hand co ordination has been very poor.
Then there is another area Games , they talk about field games like , Basketball , football, baseball etc. Even my kids are not too much into these games.
I need a tutorial on how to get indulged into these American pastimes so that I get enough insight to the point where I could have a few minutes conversation with others or at least enjoy when they are talking about these things. I do not watch those games on TV because I do not know what is going on.
Where do I start.
