In the Berlin Level on Story Mode grind the pipe next to the Billboard above the train tracks to cause a serious Destruction!

Destroy Boston (kind of)
Catch your self on fire, using the fire you used in Balls of Fire. Then grind the two cannons. There will be a cutscene then part of Boston will be dismantled.

Star Wars Kid Cameo
On the Boston level, turn right from where you first start. Go past the museum into an opening that looks like a typical apartment. Skate to the right of the door you can't go in, come down and skate up that ramp and, at the top of your jump, R2 to level out. You'll break through a glass window and find the Star Wars kid sitting there.

Glitches
Explore part of LA's background.
1: Unlock Los Angeles in Classic mode.
2: The are four rails near the starting point of the stage that cause a tremors, grinding all four of them causes the overpass (or highway) to colapse. (One of these rails goes through the small building, one to the left of the building and two are to the right of the building.)
3: Get on top of the building near the overpass then jump on it.
4: There is a ramp on the overpass that leads to a building top, jump this ramp to get on top of the building.
5: Once on top of this building, hit "Pause", hit "Your options" and hit "Set Restart". Then Pause again and hit "Retry Level". This will restore the overpass.
6: Now pause and hit "Goto Restart" under "Your options." You will now be able to jump onto the unfallen overpass, do so.
7: If you've noticed, going right knocks you out of bounds, but going left just hits an invisible wall that does nothing to you. However, there are cars that just pass right through it. If you grab on to one of the bummers (or skicth) of these cars, so will you. You will now be able to explore part of LA's background.

Get outside of the play area in create a park
First off you need to go to the create-a-park mode, then you need to pick a spot right by the fence and rise the ground up one,and right next to it by the fence lower the ground one. Next grind the top ledge going straight to the fence and quickly jump off your board after you pass the fence ,going out of the play area.

Glitch in Barcelona. (Do any grab trick on the groung. And you can not bail!!!)
1. Go to the dragon fountain at barcelona.
2. Get off your board and climb on the dragon.
3. Jump on the dragons nose while off the board.(do NOT walk)
4. When you go up in the air do a grab trick and hold on to the grab until you get to the ground. (If you do this right you will not bail.)
5. Now keep on doing tricks and you will be on the ground doing these tricks. You can do any grab and the best part is that you can never bail.
6. If you stop doing tricks or get of your board you will lose the glitch and have to do it over again.

Behind The Scenes In Hollywood
If you unlocked Hollywood, go there. Then, Go on top of the brown building pretty close to the large highway. Try to jump onto the highway from the building. If you get on the highway jump onto a car. (There's a DC truck with an opening at the back, you can jump in there, but you don't have to) once your on a car/truck just stay on it. it will take you down the highway and turn really fast, that's your Q to jump off. When you do, just get off the end of the highway and walk "behind the scenes of Hollywood!" *Hint: Don't create an earthquake before doing this, it won't work, and this doesn't work in 2-Player.*
