Some videos just have you scratching your head thinking, how did this happen?

It all went down at O'Hare Airport in Chicago.  A catering truck went berserk on the tarmac and it all was captured on video by a passenger on a neighboring plane.

It was almost like a possessed Halloween Ghoul grabbed the reigns, but apparently the accelerator was just stuck. Employees couldn't get close enough to jump on and stop it.

Finally, a hero arose from the confusion and rammed it with another vehicle. None of the workers were injured.
