When the mother of the newest missing girl arrives at the sheriff's station to make the complaint, Leo is the deputy at the front desk. In the next scene, Keith goes to find Veronica who he finds at Leo's band's practice. Leo is there, in street clothes, playing the drums.
Keith says to Don, "You've never seen Spinal Tap?" but the actual title of the movie is "This is Spinal Tap".
When Veronica brings Leo the food to give to her dad, Leo's computer monitor shows a "Low Battery Warning" from the Mac OS X operating system. There is no laptop in the scene. Desktop computers don't get low battery warnings.
The employee at the music shop's guitar has sound coming out of it, and not the amplifier which must be at least ten feet away.
