Evidence of Things Not Seen - S4-E20
Continuity mistake: In the closing minute, when C.J. Is trying to stand the egg on its end, the camera pans to the clock for DC, and it reads 12:00. But as she sits at the table, her watch reads 7:15. Then, in the next camera shot, zooming in onto the egg, you can see that C.J.'s watch reads 7:25.
