A good third language?

Okay, my main two languages are Ruby and C++. Although I've learned Ada out of school and I'm learning Scheme in school now, I don't consider them languages I'm generally GOOD with. So I'm wondering what third language I could learn to balance myself out.

I don't like your attitude.
It's true that newcomers always argue about fucking nothing because of their own ignorance. But this isn't an excuse to let older “proven” knowledge untouched.
