I can sing tenor, alto, soprano, and higher than the piano. (it's not pretty by then, though. XD) I can imitate pretty much any voice. Elvis and Russia are two of my favorites. I can make someone cry with less than 10 words if I know them well enough.
I'm not sure if it's even a talent, but I can turn both of my feet's little toe sideways, like I can create a big gap between the little toe and the rest of the toes. I have asked a bunch of people if they can do it, but usually they can only move it a bit, up and down, or not move it at all.
I tried making chocolate chip cookies minus the chocolate chips and they ended up as what I call stone sugar chip cookies. They were hard as rocks and the sugar was clumped up somehow. (They were good with tea though, so it wasn't a complete loss )
