Good language to start with?

I have a lot of free time on my hands right now, and I thought rather than letting it go to waste, I'd like to do something constructive, and learn some programming skills.
What's a good programming language to learn as my first?

I don't know if the text boards are like the image ones, if so I'm expecting a lot of rage and unhelpful comments.

Alright thanks, I wasn't expecting responses so quickly.
I'll read through SICP as recommended and do the exercises.
Is Clojure more useful than Scheme, or is it just a good learning experience trying to do the exercises in a different language?
