Awesome links, guys! Thanks!
I've had to pick up a little Spanish for my work (keeps me from getting mauled) but pretty much all I know is:
"I'm here for the lights"
"Do you have a dog?" and
"Is the dog big or small, good or bad?"
Oh, and "Where's the bathroom?" for when I'm not working.
I'm thinking that might make a good, relevant skill for me, though I'm also considering German since my dream jobs all involve dogs.
(Not saying dogs speak German, just that I was under the impression many dogs are trained using German... oh, never mind)
