Oh my God, am I the only one to spot this?
Ok here we go. At the scene where Jim asks Finch if he can teach him tantra some time, a couple of seconds after this part we hear a very deep voice mumble "JIM". Now then, we know for a fact that the voice isn't Finch's or Oz's because they don't open their mouths, and the voice is way too deep to be Stifflers. But however, if you have the Video box that has the tape 'Stifflers Guide to Sex' on it, the deep voice in the movie matches the deep voice in which the director has. You've just made a big mistake Mr Director guy.
Yep, a BIG OOPS !!!
