First off: You need a hack for this (I use Qwerxy) said hack must have at the bare minimum a speed hack (Although an airwalk is helpful, too.)
Step 1: Go to Tanaris.
Step 2: Theres an alliance dwarf flight master...target her.
Step 3: Use a ranged attack. Preferably a cast spell so you can run away before it finishes casting and escape.
Step 4: Enable Speed hack to max, and enable airwalk. (if you have it)
Step 5: Float as near the exit as you can, cast the spell and RUN out into the desert
Step 6: Enjoy teh epic lulz
I'm pretty sure you can only get 6 gryphons out on once, but either way, heres what it looks like:
Edit:
With all 6 gryphons out I watched an alliance human try to talk to her for about 2 minutes till they went away. He kept /rude'ing me.
