How will the producers of NCIS make sure that fans tune in to the show they don't switch the channel after the end credits and stay put for NCIS: Los Angeles, the spin-off? One way will be with crossovers. We've already reported the Rocky Carroll will appear on both shows, now comes word that NCIS mainstay Pauley Perrette will do a two-episode stint on NCIS: L.A.

And they aren't waiting for the guest stint. In the second episode, Perrette's brilliant, goth scientist character, Abby Scuito, will do a "fun little cameo" according to exec producer Shane Brennan.
