Saint's Row Easter Egg - Walk Trough a Wall

Enable the raggdoll effect cheat and go to the railwaystation that is near the church. Follow the railway (look out for trains) until you reach a clothing shop. Now use the superjump (raggdoll must be enabled) just press X and right after that RT or LT. With this superjump you can get on the roof of the shop. On the roof you find a door. YOU CAN WALK TROUGH IT! All the walls on that roof are actually "not there," you can walk through it what is very funny. why? normal (without the superjump) you cannot get there.
