Mourn A Sön
Mourn A Sön are one of the leading manufacturers of spinning coasters, and pretty much bollocks-all else. They were formerly known as Maurer Söhne, but they felt the new name more accurately reflects what happens whenever they build a coaster. They are currently competing with Intamin for the all-time top kills trophy. Mourn A Sön currently have a kill streak of 6.
There is an urban myth that driving to theme parks is unsafe. However, it has been scientifically proven that you are 1,000 times more likely to die riding a Mourn A Sön coaster than you are actually driving to the theme park itself.
They have also recieved attention recently for creating the X-Car, hailed as the most universally disliked rollercoaster ride system ever created. The website for the X-Car boasts "outstanding quality, award-winning design, comfortable seats, revolutionary restraint system, stadium seating, extreme manoeuvrability" and often Mourn A Sön's rides have been known to extremely manoeuvre you out of the train.
