CSI: Miami

If you look closely at the scene just after Calleigh and her dad have looked at his car and decided he's hit something, Horatio is speaking to Yelena and in the right hand corner of the screen you can see Calleigh enter the scene, but she waits behind the flagpole until Yelena exits, then she walks up to Horatio. It's a little glitch, but it's acknowledged by the director on the DVD commentary as one of the scenes he didn't block very well!
