Irish sports are fierce. This is not the Cristiano Ronaldo, Ginobili, act-like-I'm-dying-to-draw-a-foul crap. The most popular sports here are rugby, hurling, Gaelic football (which might be another post), and soccer. I should note that even though they don't take many dives in soccer, it's still not very good play. Professional athletes are often not paid and they play for the teams in the county in which they live. Because the money isn't in Irish sports the way it is in others, you don't see any Steinbrenners or Russian oil tycoons ruling running the show and there is much more pride in hometown teams.
Hurling is considered the fastest sport on grass. It's played on a 130m x 90m field, or pitch, with a ball kind of like a baseball and all of the players have big clubs they use to whack the ball up and down the field. Each side tries to either get the ball through either a) a goal that looks like a soccer net, or b) a field goal that is mounted on top of the soccer-like goal. If you get it in the net, it's worth three points, else it's worth one through the uprights. Even though players are not allowed to hack at each other with their clubs, there are a fair amount of clubbings on the field. In fact, as a defensive strategy, the players often try to run through an opponent's swing as he's trying to hit the ball instead of laying back or jumping up in the air (I told you they're intense).
Here's a video of some highlights... don't mind the music.
