You know in Nagrand, there's a Jump-a-tron 4000? Get:

1x http://thottbot.com/i34480
1x http://thottbot.com/i21569
30x http://thottbot.com/?s=Firework

And go sit on the bird nest, shooting off fireworks .etc

Also you can watch people fall to their deaths...errr....ignore this bit.

AND you can summon out the bird to scare people.

As for how to get up there....just do this:
1) Stand on the Jump-a-tron exactly facing the nest
2) Change your viewpoint to that of your char and look downwards
3) Draw a big X on your screen to show the middle.
4) Launch yourself (aim at the nest, remember)
5) 1 second before the nest is in the X, then click the buff off.
6) Hope not to die.
