If by "big bosses", you mean your boss's boss, then I would be thrown out of the company for sure if I ever did that. Your boss probably wouldn't like you going over his or her head in regards to salary without talking to them first. This would likely result in bridges being burnt.
What you did worked in your situation, and I am happy for you, but this surely shouldn't be considered a "guideline" on how to get a raise. It seems like a dangerous game of roulette, IMHO.
A little off topic but peacemaker i clicked your link about not judging peopl but it turned out to be the one about not stealing!
Why did i tell you this? Because knowing is half the battle!
