Halloween is just a few days away, and Ford decided to conjure a festive mood by pranking some of its own customers. Get ready to have a good laugh at other people's expense.

Ford Motor Company [NYSE:F] asked a handful of marks to stop for a free car wash on the way to a filmed test drive but, of course, nothing is ever really free. The car wash was tricked out like a haunted house, complete with mysteriously-flashing strobe lights. The windowless space makes a pretty good haunted house, actually, as long as everyone keeps their windows rolled up.

It doesn't take long for the participants to realize that something is up, and right when they do, they're set upon by what appear to be a mix of zombies and Lovecraftian hobos. They jump on the cars' hoods and pop out from back seats. You just never know who you'll meet at the local car wash.

Needless to say, the vehicles' occupants were pretty confused; one person said she'd never drive through a car wash again. At least the monsters stuck around to vacuum interiors.

So drive carefully this Halloween. You might encounter the undead, some otherworldly threat or, worse, a car company looking to get some cheap YouTube laughs.
