From your spawn point, travel north until you are almost at the tunnel, then move east and walk into the second house you find. If done correctly, the "A Goat Amongst Legends" challenge will start. Go up to the second floor, and press R at the television to play "Flappy Goat". This is easier if you do not have any other powers available, or rebinding the "Action" key to something else. Also try knocking the sofa and table out of the way, and zoom in to the television for a better view. Make it past ten obstacles in the mini-game without dying to score 10 points.
