Java, then Clojure. I've never used Clojure, but my understanding is that it's a Lisp dialect that targets the Java VM.
Do learn a language like Lisp, Ruby, or Ocaml, though. Once you get used to the functional paradigm, you'll realize how much more powerful these languages are, and you'll never go back.
Yup, you'll never look back! ...unless you need to get a job, of course...
Though Python is used more and more now, you can definitely get jobs in languages other than Java and C# and such... But sadly, not Lisp or Ocaml though, at least not easily.
