This spawned out of another thread, but see my sig.
Our teams have played 8 times in the playoffs (more times than 49ers-Cowboys), and 3 of our 4 Super Bowls went through them. We ended their quest for a 3-peat in 1990 and beat them in the NFC Championship Game twice in their house (both times on field goals after they turned the ball over), ruining 14-2 and 13-3 seasons. We gave them their worst playoff loss in their history. We ended Joe Montana's 49er career. Believe me, they hate us plenty. They may never admit it, but it's arguable they hate us most of all.
