What language should I learn?

I'm a graphic design major (not really tech, I know). Lately I've been getting really lazy and have been doing nothing in my spare time except pvp on WoW.

I figured learning a new language would be a good idea, and might help me in the future with landing a job. What would be best to learn? Maybe something like html perhaps? I basically want it to compliment and strengthen myself as a graphic design artist, broadening my abilities within the appropriate spectrum.

I think the question and the way this thread is approaching it is flawed in an academic sense: don't learn a language, learn how to program.
