Ruby

I've been thinking a lot about this recently: I feel that it's a severe hole in my programming knowledge if I don't know any object-oriented languages.

I only know C. Which isn't object-oriented. What am I going to do about this? I think I'm going to learn Ruby, as its apparently 100% OO'd and nice to write in.

I'll let you know how it goes!

Erm, can anyone recommend any books?
