Dial-A-Human.com is just like Gethuman.com, offering a cheat sheet of secret codes to bypass annoying phone-trees and get right to a live operator.

While their databases are basically the same, I did spot a few differences, so if you try the combo on one site and it doesn't work, check the other's.

Bonus link for iPhone users: check out Dial Zero, a free app pre-programmed with the codes to directly dials human customer service reps at over 600 companies.
