Near the middle of the movie, Ted (Ben Stiller) picks up a psychotic hitchhiker (Harland Williams). Ted and the hitchhiker get into a little discussion about "7 Minute Abs..." if you've seen the movie, you know what I'm talking about. Anyway, the mess-up comes when Ted pulls over to take a leak at a rest area. When the car pulls up to the camera, the hitchhiker says, "What are these seats made from? Cactus?" If you look at Harland's lips, they don't even move when he says this line! Weird, huh? Check this one out for yourself.
