In the scene when Eddie and Clark are getting food at the all you can eat buffet, they come across some disgusting looking blue and yellow stuff. The blue one has a sign that says chicken and the yellow, a sign that says beef. Clark tells the cook that it didn't look like chicken. "Oh, you're right", he says. He then switches the signs. Look at his hands, we see him switch the two signs and put them is place, but when the camera backs away to behind Clark's head, the cook is still switching the signs.
