Call this the ultimate prank.

How do you think you would react if you were in the back seat of a small plane and the pilot fell asleep, or worse? Well, this poor guy got to find out.

In this video posted on Reddit, one brave idiot scared the crap out of his buddy as they were flying in a small plane.

Some people on this thread said that this video is probably fake, and that the passenger was in on the prank, but I'm not so sure. That guy screams for his life pretty convincingly if you ask me.

Now that you're here, sit back and enjoy watching these people get the pants scared off of them:
