By this, I mean those talents that aren't really typical. So, instead of saying you having an apt for guitar or can sing, you can say something less traditional that you do particularly well, be it hacking, forging signatures, mimicking voices, etc. You know, the talents you wouldn't really list for your parents.
One of my nontraditional talents include accents. I can do accents really, really, REALLY, well. I have a large range too. It may seem weird or stupid but whatever, I can sound British/Arab/Indian, you name it.

What are some of yours?
