"But everybody hated me for it..saying it dissed the japs...so I changed it to my current one...and Ive had it ever since..."
Actually, calling the Japanese "Japs" is more offensive than your actual past-signature.
And yes, at one time, I did have a signature. I believe it was:
"I am Nobody
Nobody is Perfect
I am Perfect"
It was a joke, more or less, but people seemed incapable of understanding it, and so, I've taken my current signature.
