Falling down a flight of stairs is no laughing matter. One unfortunately misplaced foot is all it takes, and a painful one way trip to the bottom of the stairs will follow. Falling down the stairs - as anybody who has done so will surely testify to - isn't all that much fun. That said however, it can be pant-wettingly funny to be the one who happens to witness just such an event. Secret Exit were obviously aware of this, and were decent enough to provide iPhone owners with Stair Dismount; a game all about pushing crash dummies down stairs in humorous ways.
