Does anyone have a photoshop serial?

Does anyone have a serial number of their Photoshop that I can enter into the screen that comes up? I would really appreciate it...I don't have much money, that's why I was wondering.

Okay....first which photoshop is it. Second you can find this on the net if you want. I personally used limewire to nab a serial number for CS when I had it. Worked fine. Just make sure to scan the file with norton before opening it.
