This may take some time to load, and isn't completely one-switch accessible - but it is a laugh. You are standing at a bus stop in Korea with terrible wind building up. Use the space-bar to fart - but only do so if the sound will be muffled by passing traffic. Try not to be discovered. Pressing the left arrow seems to let out a silent fart, but you can only do this so often... So now you know my level of humour!
By the way, if anyone out there has the skills to hack this game - I'd love to see the menu simplified so that the whole game is accessible via the SPACE BAR and LEFT cursor key.
