I know enough Hangul (Korean) to order food, ask the time, and far too many grammar rules. I can also read/speak it quite well, so if I need to learn a word or phrase on the fly, I can use one of my apps to get the word/phrase I need.
Was learning in my free time from a friend that spoke Korean. Though we don't work together anymore, and that's not a language you want to teach yourself with no prior background.
EDIT: Just realized I'm assisting in a mass necro-post.
