If you're an expat and you haven't already checked out this website, then you should!  It has lots of hilarious comics depicting the daily struggles and cultural issues that befall foreigners in Korea.  I like a lot of them because I can personally relate to the sentiment expressed, but I think right now this is my favorite.  Many a time I have boarded a city bus in Gwangju and barely been able to make it to my seat before the driver takes off in a hurry.

Don't just take my word for it, check it out for yourself!
