In the scene where the guy whom wife Leon Phelps sleeps with last goes into the V.S.A. meeting and the people are talking, if you look in the top left hand corner of the screen you can see a microphone hanging down in the corner.

In another scene (I can't remember which one) another microphone is hanging down from the same corner in the scene.

What makes this even funnier, working at a movie theater, a lady came out complaining about this thinking it was our fault. These mix ups are that obvious!!!.
