Start a "who's going to be the next to get serious bodily harm" pool (I'd put some on Greg lol...he's already got the most hospitalizations in the LV lab I think.)
Tell DB or Horatio that Mac Taylor does it better.
Tell Horatio that he doesn't know how to wear sunglasses like the master, then show him Mac's picture.
Let a bug go in DB's office. Then find it and say something like " I guess Grissom didn't know he lost this...good thing we found it, it's highly poisonous. I sure hope there aren't anymore loose."
Address Ray as "Dr. Morpheus" Then ask if he wants the blue pills or the red pills.
and OK I got the bug bomb one twice. My bad.
Ask Danny about "That time he was undercover in Vegas as Thumpy G." Especially while Lindsay's in the room. Then sit back and watch her ask him a bunch of questions. Or alternately, get Mac to send him to LV on a case and see how many times he gets called Thumpy G. (OK so there was never any connection made between Revenge Is Best Served Cold and CSI NY...it's funny anyway.)
Tell Danny and Lindsay they can't ever work another case together again.
